Prototypes and provocations: imagining the future of synthetic biology

“Ultimately, the rate limiting factor for the future development of synthetic biology may actually be human creativity.”     
-David Drubin et al. “Designing Biological Systems.”

Synthetic biology is often defined as the application of engineering principles to biology. Such a practice is intended to facilitate the future design of biological systems for a range of applications in the production of fuels, foods, materials, and medicines. Within this paradigm, designs of genetic systems built from modular parts start as prototypes (from the Greek πρωτος –“first” and τυπος –“impression”): simplified models meant to interrogate the value of such an approach and provide measurements and tools for the refinement of future engineered systems. But such prototypes also act as provocations, asking us to imagine a future where anything can be built with biology. The work of artists and designers exploring the potential of synthetic biology take such provocations further, creating scientific fictions in the form of narratives, objects, and films rather than the concluding sentences of journal articles. These design fictions question the role new biotechnologies will play in industries and in our everyday lives, imagining changes in the ways that we interact with our bodies and health as well as with consumer products, our homes, and our cities. These prototypes and provocations–by engineers and scientists or by artists and designers–can capture the imagination of wide audiences, influencing the design of new gene networks, the curation of gallery exhibitions, the founding, funding, and regulation of research institutions and startup companies, and existential fears about the hubris of attempting to control nature. In this talk I will use several examples of recent projects from artists and scientists to explore how creativity, narrative, the media, and provocative objects inspire the future of synthetic biologies.

Rewiring metabolism to improve crop yield in Africa

Microbial fermentation has been exploited by humans for millenia for the production of food, fuel, and chemicals. Despite intense research efforts, the spectrum of compounds produced in this way is still limited to either naturally occuring fermentative pathways or shows low yields due to genetic regulatory contraints imposed by the host strain. I will discuss our efforts in designing synthetic metabolism and rewiring regulatory architectures in microbial cells to allow high yield production of compounds. As an exemplar, we have engineered a synthetic pathway to the plant hormone strigolactone as a step towards improving crop yield. The parasitic weed species of the Striga genus are among the major biotic stresses on crop yield in Africa, affecting staples such as maize, sorghum, rice, and cowpea. Striga seeds lie dormant in soil until they detect the plant hormone strigolactone, which induces seed germination and attachment of the weed to host roots. The application of strigolactone to farmland before planting can induce ‘suicidal’ germination of Striga seeds. However, the high cost of chemical synthesis of strigolactone has precluded the use of this strategy in the field. The low cost, microbial production of strigolactone can be used in a program of Striga eradication from arable land in Africa.

Designing Technologies for Societal Challenges: From the bicycle to synthetic biology

All technologies are designed, and so are the products of synthetic biology. Designers make crucial choices that result in values being incorporated in technology, and which have implications for technology’s role in society. Since all designs are thus inevitably value-laden, Bijker will propose that we explicitly address this question of implicit values and social and political choices in designing technologies in general, and in synthetic biology in particular. He will argue that societies need to experiment with new ways of democratically dealing with emerging technologies (like synthetic biology), and will illustrate this with the societal dialogue in The Netherlands on nanotechnology (2009-2011).

Synthetic microbes engineered for therapeutic applications

Synthetic biology aims to engineer genetically modified biological systems that perform novel functions that do not exist in nature, with reusable, standard interchangeable biological parts. The use of these standard biological parts enables the exploitation of common engineering principles such as standardization, decoupling, and abstraction for synthetic biology. With this engineering framework in place, synthetic biology has the potential to make the construction of novel biological systems a predictable, reliable, systematic process. While the development of most biological systems remains largely ad hoc, recent efforts to implement an engineering framework in synthetic biology have provided long-awaited evidences that engineering principles can facilitate the construction of novel biological systems. In this talk, our recent efforts to develop therapeutic microbes with programmable functionalities will be presented. In particular, an emphasis will be placed on our development of synthetic probiotics, equipped with clinically relevant functionalities such as pathogen detection, antimicrobial molecule release, directed movement, and biofilm reduction, that showed effective antimicrobial activities against target human pathogens in in vitro and eukaryotic infection models. This development suggests the possibility that probiotics could potentially be engineered for prevention and treatment of target infectious diseases, which may provide an antimicrobial strategy that is complementary to current antibiotic therapies.

Reprogramming the Genetic Code

The information for synthesizing the molecules that allow organisms to survive and replicate is encoded in genomic DNA. In the cell, DNA is copied to messenger RNA, and triplet codons (64) in the messenger RNA are decoded – in the process of translation – to synthesize polymers of the natural 20 amino acids. This process (DNA RNA protein) describes the central dogma of molecular biology and is conserved in terrestrial life. We are interested in re-writing the central dogma to create organisms that synthesize proteins containing unnatural amino acids and polymers composed of monomer building blocks beyond the 20 natural amino acids. I will discuss our invention and synthetic evolution of new ‘orthogonal’ translational components (including ribosomes and aminoacyl- tRNA synthetases) to address the major challenges in re-writing the central dogma of biology. I will discuss the application of the approaches we have developed for incorporating unnatural amino acids into proteins and investigating and synthetically controlling diverse biological processes, with a particular emphasis on understanding the role of post-translational modifications.

Synthetic yeast Chr XII and beyond

Recent advances in DNA synthesis technology have enabled the construction of not only the genetic circuits or pathways, but also the entire genome in an organism, leading to the new era of genome engineering. To further our understanding of the eukaryotic genome, an international synthetic yeast genome project, Sc2.0 was initiated. Work on 8 of the 16 Sc2.0 chromosomes has been begun by teams in the U.S., China and the U.K. Among the yeast chromosomes, Chr XII is the largest one, which contains about one million base pairs of DNA plus more than 100 copies of the 9.1kb ribosome DNA (rDNA) repeat. Here we describe our strategies to synthesize this giant chromosome. To facilitate the assembly of the synthetic chromosome, we explore the “awesome power” of homologous recombination in budding yeast.  Instead of synthesizing the mega-chunks as designed before, we developed an over-lapping integration strategy. In addition, laborious DNA extraction/cloning procedures were substituted by new “one pot” in vitro assembly method, leading to the fast and efficient replacement of the endogenous chromosome.  Furthermore, we will discuss multiple designs applied to the rDNA repeats, trying to further our understanding of this specific DNA region.

Innovation in Global Healthcare

Innovation has delivered incalculable benefits to billions of people.  But the demands of this century will require even greater change because many health systems are rapidly becoming unsustainable.  Not only does the non-communicable disease epidemic threaten to overwhelm health services.  The costs of care are also rising, and this at a time when many countries face perhaps a decade of fiscal consolidation.  In his talk, Professor Darzi will discuss these drivers of innovation, arguing that more of the same will not be enough to restore health systems’ sustainability: fundamentally new ways of delivering care will need to be found that are at once better and cheaper.  Although this is clearly a challenge that has not yet been met, Professor Darzi will point to innovations from the emerging world with the potential to reshape health services in developed countries.  A key part of the answer will be to close the gap between what we know and what we do—and focus on the uptake of innovations every bit as much as on the basic research which gives rise to them.

He is a member of the European Molecular Biology Organisation (EMBO), the American Academy of Microbiology (AAM) and the European Academy of Microbiology (EAM).

One of his longstanding interests is the development of standardized molecular tools for deep genetic and genomic refactoring of Gram-negative microorganisms, in particular Pseudomonas putida. He is currently trying to develop an all-prokaryotic artificial immune system based on parts and devices mined from environmental bacteria.

Syn Bio standards for engineering complex phenotypes in environmental bacteria

The prokaryotic world is the largest reservoir of enzymatic activities in the Biosphere, but the vast majority of this treasure trove has not yet been exploited. To overcome this state of affairs new conceptual and material tools, as well as understanding of a large number of fundamental biological processes (e. g. metabolism) are required. Key aspects include optimization of a limited number of genomic and biochemical chasses compatible with environmental applications, standardization of methods of physical assembly of DNA constructs, development of genetic tools for deployment and stable maintenance of the implanted traits and adjustment of the engineered property to the genetic and biochemical background of the host. In this context, we have developed a large number of molecular tools for designing strains of the soil bacterium Pseudomonas putida aimed at biosensing and / or biodegradation of recalcitrant chemicals that are environmental pollutants. This multi-tiered effort involves [i] editing and streamlining of the existing genome for deletion of non-desirable segments (eg prophages) and enhancement of beneficial functions (eg stress tolerance), [ii] adoption of the so called Standard European Vector Architecture (SEVA) format for analysis, construction and deployment of genetic constructs in Gram-negative bacteria other than E. coli and [iii] development of fusion partners for targeting expression of given proteins to various cell compartments. The value of such standards (as well as their shortcomings) will be exemplified in our efforts to biodegrade anaerobically the environmental pollutants 1,3-dichloroprop-1-ene with a heavily engineered P. putida strain.

From Context-dependence to Modularity in Biological Circuits

The ability to accurately predict a network’s behavior from that of the composing modules is a major challenge in systems and synthetic biology due to individual modules exhibiting context-dependent behavior. One leading cause of context-dependence is retroactivity, a phenomenon similar to loading that affects the dynamic performance of a module upon connection to other modules. Retroactivity is particularly daunting for synthetic biology, in which working modules often fail to function as predicted once interacting with each other.  Here, we illustrate analysis and design techniques to mitigate this problem along with experimental demonstrations. First, we introduce a simple analysis framework, conceptually analogous to Thevenin’s electrical circuit theory, which accounts for retroactivity to quantitatively predict how a module’s behavior will change after interconnection with other systems. Experiments carried both in yeast and E. coli validate this theory and demonstrate that retroactivity substantially deteriorates the dynamic response of gene circuits. To solve this problem, we introduce a load driver device to connect a circuit to a variable number of systems (load) in such a way that the circuit output is reliably transmitted to the load while preserving the unloaded system performance. The load driver design is based on fast regulatory elements that reach quasi-steady state quickly in response to slow changing inputs (principle of time-scale separation). These fast elements are in sufficiently high concentrations such that the quasi-steady state is unaffected by load. We built and experimentally tested in Saccharomyces cerevisae an instance of a load driver with circuitry based on (fast) phosphotransfer reactions. We first built and tested several transcriptional regulatory networks and demonstrated that their responses were severely impaired due to load. We then demonstrated that incorporation of our load driver restored response dynamics, thus remedying the load problem.

In this talk, I will outline an example of how starting with a high level specification of a desired synthetic genetic circuit, a fully realized DNA sequence can be produced with minimum human interaction in an academic environment. Key to this process is the formalized expression of primitive building blocks, functional equivalence, assembly plan optimization, data persistence, and liquid handling protocol generation. In addition, I will hypothesize on how this process can be scaled to industrial settings and outline the current software ecosystems I see emerging in the field.

Engineering switches to bring designed complexity to synthetic biology

As we construct the first synthetic eukaryotic genome with the Sc2.0 consortium, how do we plan to add new functions to the minimal genomes that are created? While much larger, our own genome contains less than 23,000 genes, yet it encodes for many of the most complex systems we know. The key to this immense complexity is gene regulation, and recent work has estimated that the human genome contains nearly 4 million switches that control where and when the genes are turned on and off in a myriad of ways. Engineering composable switches is the key to bringing designed complexity to synthetic biology. To do this we are taking a bottom-up approach; using bioinformatics tools to first identify minimal promoter sequences and then using these as the framework to rationally engineer dozens of new synthetic switches. Starting in S. cerevisiae, we have developed a workflow to rapidly generate promoter libraries during the process of DNA assembly. Mutation then guides where we target these promoters with a combinatorial TAL-Effector library that offers 1-to-1 repression of the intended gene.  Wiring these synthetic switches together in increasingly large constructs enables us to understand the current limiting factors for engineering complexity – orthogonality, noise, burden and genetic instability – and guides us to generate new designs that account for these factors.

The social life of standards

Standardization is a key principle being brought from engineering into the field of synthetic biology. Within the synthetic biology community there are several ongoing attempts to develop and implement standards, according to a range of different typologies. In this talk I want to take a step back and focus on some key characteristics of standards, and the roles they play in our daily lives as researchers, policymakers, and citizens. Drawing on examples from within and outside synthetic biology, I will show how standards are fundamentally both technical and social instruments that bridge the worlds of things and people. As well as being important technical instruments for achieving reliability, predictability and control in engineered systems, standards are also associated with social and political institutions of power, accountability, credibility, and trust. Indeed, standardization has become a key form of governance in modern societies, and its implications reach far beyond laboratory practice. During their development, standards require a theory or imagination of how they will be used; in their implementation, standards are necessarily always partial, vulnerable to resistance, and open to revision. These characteristics have implications for how the synthetic biology community chooses to approach practices of standardization – what kinds of values might we strive to build into standards for synthetic biology (technical standards, safety standards, ownership standards, and so on) that could help to promote ‘biotechnology in the public interest’? And whose expertise should be involved to develop standards that are effective and equitable?

The International Gene Synthesis Consortium (IGSC): Development, Implementation and Operation of Biosecurity Protocols in Industrial Gene Synthesis

Gene synthesis at increasing scale is a foundational suite of technologies and capabilities, advancing diverse research and industrial applications in synthetic biology engineering of living systems.  Gene synthesis is a typical “dual-use” technology, simultaneously applicable for greater good and fulfillment of the promise of synthetic biology while potentially misused or intentionally designed for nefarious purposes.  As current national and global guidelines, regulations or oversight are either in early development or don’t yet exist, awareness among community stakeholders regarding dual-use issues and the related need for effective biosecurity protocols is high.  The leading synthetic gene providers proactively formed the IGSC in 2009, developing and implementing “The Harmonized Protocol”, a common parameter set for sequence homology-based gene order screening and customer information analysis among IGSC member companies. The Harmonized Protocol was in large part mirrored in the development of the Screening Framework Guidance for Providers of Synthetic Double-Stranded DNAb published in 2010.  Since this time, membership in the IGSC has grown and the consortium enjoys continued regular engagement and collaboration among its members and with regulatory, policy, enforcement and academic stakeholders across and beyond the synthetic biology community.  The common tools and implemented biosecurity screening processes used by the IGSC for compliance with national law, including export control regulations and international guidelines will be described.  Development and implementation of a common and shared biosecurity sequence database and flag alert system operating in the context of member companies’ order process and supporting decision guidance by safety officers and informaticians to effectively resolve a concern sequence order or customer profile will be presented.

Crop Biotechnology and Civil Society in Africa: Surveying Systems of Innovation for Development

Given growing food insecurity, countries in sub-Saharan Africa are increasingly using advanced biotechnologies and genetic modification to develop new crops.  Innovation surrounding new and emerging biotechnologies is complicated not only because of technical capacities, but also because of the diversity of organizations and institutions involved with different priorities and strategies.  Using a systems of innovation approach, this presentation analyzes several agricultural biotechnology projects in Kenya.  It demonstrates that while these projects have facilitated new connections between organizations and new knowledge pathways critical to innovation, the projects result in innovation for its own sake – valuing the process of innovation over the intended benefits, in this case improved livelihoods of farmers.  Researchers, companies and civil society organizations need to partner in new ways in order to better incorporate the needs and values of farmers into biotechnology innovation.

Engineering simple plant systems

Synthetic Biology has great potential as a tool for the engineering of multicellular organisms. (1) The greatest diversity of cell types and biochemical specialisation is found in multicellular systems, (2) the molecular basis of cell fate determination is increasingly well understood, and (3) it is feasible to consider creating new tissues or organs with specialized biosynthetic or storage functions by remodelling the distribution of existing cell types. Of all multicellular systems, plants are the obvious first target for this type of approach. Plants possess indeterminate and modular body plans, have a wide spectrum of biosynthetic activities, can be genetically manipulated, and are widely used in crop systems for production of biomass, food, polymers, drugs and fuels.   

Current GM crops generally possess new traits conferred by single genes, and expression results in the production of a new metabolic or regulatory activity within the context of normal development. However, cultivated plant varieties often have enlarged flowers, fruit organs or seed, and are morphologically very different from their wild-type ancestors. The next generation of transgenic crops will contain small gene networks that confer self-organizing properties, with the ability to reshape patterns of plant metabolism and growth, and the prospect of producing neomorphic structures suited to bio production.   

We have developed a battery of computational, imaging and genetic tools to allow clear visualisation of individual cells inside living plant tissues and have the means to reprogram them. These techniques are well suited to study of simple experimental systems such as the lower plant Marchantia polymorpha and surrogate microbial populations. These types of simple systems are becoming increasingly important to explore the next generation of genetic circuits with self-organising properties.

Synthetic biology seeks to probe fundamental aspects of biological form and function by construction (i.e. resynthesis) rather than deconstruction (analysis). Synthesis thus complements reductionist and analytic studies of life, and allows novel approaches towards fundamental biological questions.     

We have been exploiting the synthesis paradigm to explore the chemical etiology of the genetic apparatus shared by all life on earth. Specifically, we ask why information storage and propagation in biological systems is based on just two types of nucleic acids, DNA and RNA. Is the chemistry of life’s genetic system based on chance or necessity? Does it reflect a “frozen accident”, imposed at the origin of life, or are DNA and RNA functionally superior to simple alternatives.    

I’ll present progress towards in the synthesis, replication  and evolution of such alternative genetic polymers (XNA) [1]. Such synthetic genetic polymers expand the central dogma and conclusively address questions such as the capacity of genetic polymers other than DNA and RNA for information storage, heredity and evolution.    

The work also opens up an entirely new field of “synthetic genetics” concerned with exploration of the informational, structural, and catalytic potential of these novel polymers. Synthetic genetics will not only advance our understanding of the parameters and precise chemical logic of molecular information encoding and retrieval but promises to provide a rich source of ligands, catalysts, and nanostructures with tailor-made chemistries for manifold applications ranging from medicine to material science [2].

Programming Genomes To Re-Engineer Life’s Functional Repertoire

A defining cellular engineering challenge is the development of high-throughput and automated methodologies for precise manipulation of genomes. To address these challenges, we develop methods for versatile genome modification and evolution of cells. Multiplex automated genome engineering (MAGE) simultaneously targets many locations on the chromosome for modification in a single cell or across a population of cells, thus producing combinatorial genomic diversity. Conjugative assembly genome engineering (CAGE) facilitates the large-scale assembly of many modified genomes. Our methods treat the chromosome as both an editable and evolvable template and are capable of fundamentally re-engineering genomes from the nucleotide to the megabase scale. I will present one application of MAGE to generate combinatorial genomic variants from a complex pool of synthetic DNA to diversify target genes in order to optimize biosynthetic pathways. Then, I will also describe the integration of MAGE and CAGE to engineer a Genomically Recoded Organism (GRO), replacing all 321 UAG stop codons with the synonymous UAA stop codon in E. coli. This work increases the toolbox for genomic and cellular engineering with the goal of expanding the functional repertoire of organisms.

General methodology to engineer RNA circuits and its validation in E. coli

The reprogramming of cells with novel behavior involves the engineering of synthetic circuits manipulating of DNA, RNA and/or proteins, which requires targeting nucleic acids with high specificity. RNA is an ideal molecule to be used as molecular interaction domains able to recognize other RNA or DNA. Unfortunately, RNA stability and function depends critically on global interactions, which often prevents a modular design strategy. This is particularly relevant when designing allosteric conformations in the RNA to create switching behavior. Such design could be done using computational methods. For this, we show how using standard secondary structure methods can already produce RNA switches working in E. coli if we incorporate evolutionary computation algorithms. There, we automatically optimize the sequences of a RNA circuit by minimizing their interaction activation and formation energies. Such objective function implements known RNA stability and kissing loop mechanisms. The recent engineering of self-assembly DNA interaction pathways in vitro by computational algorithms could not be extended to RNA in living cells until now. Here we report a general de novo RNA circuit design approach, where we have experimentally validated in E. coli fully synthetic RNAs displaying switching behavior. We also show in E. coli that our riboregulatory devices can be combined with known functional RNA fragments (such as ribozymes and aptamers) to create complex RNA circuits in bacteria. We also characterized their in vivo RNA dynamics by using microfluidics time-lapse microscopy to track single-cells. Our work provides a new paradigm to design functional RNAs circuits by only relying on RNA stability and RNA-RNA interactions.

Protein origami based on modular coiled-coil interactions

Proteins  are able to perform versatile functions due to the variability of aminoacid side chains and their tertiary structures that  evolved through complex cooperative interactions.  De novo protein fold design  is still very challenging. We devised a strategy to design self-assembling polypeptide nanostructured polyhedra, based on orthogonal coiled-coil dimerizing mudular segments. We designed end experimentally demonstrated formation of the tetrahedron that self-assembles from a single polypeptide chain comprising 12 concatenated coiled-coil-forming segments connected by flexible peptide hinges. Path of the polypeptide chain is guided by the defined order of segments that traverse each of the 6 edges of the tetrahedron exactly twice, forming coiled-coil dimers with their corresponding partner segments. WE demonstrated formation of discrete particles in agreement with designed shape using CD, DLS, imaing by electron microscopy and AFM. Coincidence of the polypeptide termini in the same vertex was demonstrated by reconstitution of the split fluorescent protein by the polypeptide with the correct tetrahedral topology, while polypeptides with a deleted or scrambled segment order fail to self-assemble correctly. This design platform provides the basis for construction of new topological polypeptide folds based on the set of orthogonal interacting polypeptide segments.

Metabolic Engineering aims to purposeful design or redesign biological system for the production of commercially valuable chemicals such as biofuels, platform chemicals and biologically active compounds. To achieve the successful design or redesign of the biological systems, robustness of naturally occurring biological systems has to be relieved so that cells can be easily redesigned. Although extremely huge efforts have been made to find genetic target to improve metabolic function of the microorganisms, there still exists the additional room for the non-rational approach. Currently, typical approach for metabolic engineering uses both rational approach as well as non-rational methods such as combinatorial and evolutionary methods. One of the most critical problems of metabolic engineering is especially robustness of the biological systems. Bacterial cells are generally evolved at the various levels from DNA to protein for maintaining their robustness against the changing circumstances. Therefore, general strategy to modify cellular physiology depending the robustness or flexibility of the biological systems should be required. In this study, we developed intracellular metabolite sensor named “riboselector” to regulate metabolic distribution will be presented. The potentials of the platform technology developed in this study for the application to the production of biofuels and commodity chemicals.

The State-of-The-Art in Synthetic Biology: Technology, Policy, and Practice

Realizing constructive applications of synthetic biology requires the continued development of enabling technologies as well as policies and practices to ensure these technologies remain accessible for research and commercial development. Because the field of synthetic biology spans a wide range of disciplines – from engineering and biology to mathematics and computer science – the technologies considered “enabling” by synthetic biology researchers are expected to cover a broad range. We surveyed a community of self-identified practitioners engaged in synthetic biology research in order to obtain their opinions and experiences with technologies that support the engineering of biological systems. The results of our survey show the technologies enabling synthetic biology research are evolving, with shifts in the use of physical assembly methods and software tools, widespread use of public registries, and early adoption of functional composition and data exchange standards. Many technologies are widely accessible, at least for research use, either by virtue of being in the public domain or through legal tools such as non-exclusive licensing. However, broad access to technologies for commercial purposes presents more of a challenge. Because useful applications of synthetic biology may embody multiple patented inventions, it will be important to create structures for managing property rights that will promote access to the foundational technologies needed for commercial development of synthetic biology products and services. Moreover, because synthetic biology research and development is conducted across multiple institutions in many countries, it will be important to adopt policies and practices that promote cross-institutional and transnational exchange of ideas, data, and technology. By monitoring the enabling technologies of synthetic biology and addressing the property rights, licensing practices, and regulatory policies covering those technologies, our hope is that the field will be better able to reach its full potential to promote human health and preserve the environment.

The Semisynthetic Artemisinin Project

The realization of the semisynthetic artemisinin project is a success story for global teamwork between industry, academia and nonprofit-organizations and shows examplary how an innovation on labscale becomes an industrial reality contributing to global health. Global demand for artemisinin, the key ingredient of artemisinin-based combination therapies (ACTs), has increased since the World Health Organization identified ACTs as the most effective malaria treatment available. Because the existing botanical supply of artemisinin – derived from the sweet wormwood plant – is inconsistent, having multiple sources of high-quality artemisinin will strengthen the artemisinin supply chain, contribute to a more stable price, and ultimately ensure greater availability of treatment to people suffering from malaria. The development of a new commercial-scale alternative manufacturing process to produce a complementary source of artemisinin started nine years ago, led by OneWorld Health, and funded by the Bill & Melinda Gates Foundation. The project built upon pioneering synthetic biology work done at the University of California, Berkeley (UC Berkeley), and involved a team of public and private partners, including Sanofi and the synthetic biology innovator, Amyris, Inc., to take the project from laboratory research to commercialization. This innovative industrial process to produce semisynthetic artemisinin consists in the production of artemisinic acid through fermentation – which is performed by Huvepharma, in Bulgaria – followed by a synthetic transformation of the artemisinic acid into artemisinin via photochemistry, which is performed by Sanofi in (Garessio, Italy). The realization of this project is a pivotal milestone in the fight against malaria, which affects about 300 million people every year and was responsible for more than 650,000 deaths in 2010.

Design and engineering of microorganisms for chemicals and materials

Bio-based production of chemicals, fuels and materials by microbial fermentation of non-food renewable biomass has become increasingly important due to our increasing concerns on the limited fossil resources and environmental problems. In order to improve the performance of naturally isolated microorganisms, metabolic engineering needs to be performed. Rapid advances in systems biology and synthetic biology are enabling us to approach biological and biotechnological problems at systems level with abilities to finely design and control the metabolic and regulatory circuits. Thus, it is now becoming possible to perform metabolic engineering at the systems level. In this lecture, I will present the general strategies for systems metabolic engineering of microorganisms for the efficient production of chemicals, fuels and materials. The use of synthetic small regulatory RNAs to engineer metabolism at the systems-level will also be described.

Engineering Analog and Digital Computation and Memory in Living Systems

Natural biological systems incorporate both living and non-living components to achieve a diversity of functions. For example, bone is composed of osteoclasts and osteoblasts which can sense external signals and remodel the extracellular matrix to change mechanical characteristics. Bacterial biofilms synthesize proteins, nucleic acids, and polysaccharides to build hydrated extracellular matrices that protect them from outside insults.    

Inspired by natural systems and leveraging the tools of synthetic biology, we present our efforts to engineer living biomaterials that incorporate living cells containing synthetic gene circuits with non-living extracellular materials. Central to this idea is the ability to endow the cellular aspects of living biomaterials with novel computational functions. Here, we describe scalable frameworks for constructing synthetic gene networks that implement digital and analog computation paradigms and integrated memory devices. Digital systems are useful for performing cellular decision-making and logic and can be constructed with concomitant DNA-encoded memory using libraries of orthogonal recombinases. Analog systems are useful for achieving wide-dynamic-range biosensing and complex mathematical functions. We shall present our efforts to create analog circuit motifs that perform wide-dynamic-range logarithmic transformations, addition, subtraction, multiplication, division, and power laws.    

Ultimately, our goal with these platforms is to integrate synthetic gene circuits in living cells with abiotic materials to build heterogoenous living biomaterials with the ability to sense and respond to environmental conditions, self-assemble multiscale structures with tunable mechanical properties, repair themselves, and achieve new interfaces between living and non-living systems.

Syn Bio standards for engineering complex phenotypes in environmental bacteria

The prokaryotic world is the largest reservoir of enzymatic activities in the Biosphere, but the vast majority of this treasure trove has not yet been exploited. To overcome this state of affairs new conceptual and material tools, as well as understanding of a large number of fundamental biological processes (e. g. metabolism) are required. Key aspects include optimization of a limited number of genomic and biochemical chasses compatible with environmental applications, standardization of methods of physical assembly of DNA constructs, development of genetic tools for deployment and stable maintenance of the implanted traits and adjustment of the engineered property to the genetic and biochemical background of the host. In this context, we have developed a large number of molecular tools for designing strains of the soil bacterium Pseudomonas putida aimed at biosensing and / or biodegradation of recalcitrant chemicals that are environmental pollutants. This multi-tiered effort involves [i] editing and streamlining of the existing genome for deletion of non-desirable segments (eg prophages) and enhancement of beneficial functions (eg stress tolerance), [ii] adoption of the so called Standard European Vector Architecture (SEVA) format for analysis, construction and deployment of genetic constructs in Gram-negative bacteria other than E. coli and [iii] development of fusion partners for targeting expression of given proteins to various cell compartments. The value of such standards (as well as their shortcomings) will be exemplified in our efforts to engineer P. putida strains for various applied purposes.

Streamlining and Reprogramming a Bacterial Catalyst for the Production of Bulk and Fine Chemicals

We report on the construction of a genome-streamlined bacterium cell endowed with assembled genetic circuits for the production of high added-value aromatics and bioplastics. We developed and validated experimentally a genome-scale, model framework of the metabolism and transport of the biocatalytic chassis, Pseudomonas putida. Predictions pin-pointed interventions that, once implemented in-vivo through combinations of mutants and feeding strategies, enabled re-programming of carbon metabolism for a stark increase in the production of high-value precursors of bioplastics and fine-chemicals. To simplify and stabilize the chassis, we streamlined the 6-megabase genome through a newly developed excision method based on the combination of customized mini-transposons and the FLP-FRT site-specific recombination system. After 4 cycles, we shed 8% of the genome, thereby simplifying cellular wiring with no negative impact on the fitness. Genome-wide analyses of the streamlined chassis – through combined mathematical modelling and experiments – yielded new insights into the metabolism and regulation of this industrial bacterium. In parallel, we developed and experimentally validated a detailed dynamic model of the circuit coded by the pWW0 plasmid (a plug-and-play circuit for the biotransformation of aromatics). The model revealed that the architecture of the key regulatory node of the promoter system Ps/Pr can discriminate between alternative and competing carbon sources, which is of utmost relevance for biocatalyis of aromatic-derived fine chemicals. The study of the interplay between the biocatalytic circuit and the metabolic wiring of the chassis revealed unexpected mechanisms that control the expression of the “plugged-in” circuit. This workflow generated a streamlined bacterial factory, devoid of unnecessary gene complements and undesired cross-talk, thereby enabling a higher degree of control and, hence re-programming, by plugging-and-playing at will.

Ethics and governance of emerging biotechnologies: Lessons from regenerative medicine and genetics

Just as the founders of a scientific field are responsible for laying the experimental groundwork for that field, so too do they have a responsibility for laying the ethics and governance groundwork. As synthetic biology grows and matures as a field, it can learn from other areas of biomedicine about how early decisions can shape downstream development and use. In this talk, I will draw on the experience of the regenerative medicine and genetics communities for lessons for today’s synthetic biologists.

Spatio-Temporal Engineering of Biochemical Reaction Networks

The reactions of molecules in the cell occur in highly non-uniform settings.  Enzymes, cofactors, and substrates are rarely present at uniform concentrations throughout the cell but rather are spatially organized into regions of high and low concentration.  These concentration profiles and the ways in which they are temporally regulated are essential to the normal operation of the reaction networks that underlie cell function.  Yet, mechanistic studies of the unique factors that stem from spatio-temporal structuring of reactants are challenging.  This seminar will describe a model system wherein enzymes act on immobilized substrates, with several unusual features.  We show that a kinase which can associate with the phosphopeptide it generates will display an autocatalytic reaction profile.  Further, the reaction generates spatial patterns of the product and shows an initial rate that varies with geometrical pattern, but not the ratio, of substrate and product.   When reactions are performed in the presence of an opposing phosphatase, the direction of the phosphorylation reaction shows a dependence on the density of the substrate.  This last observation points to a new motif for regulating phosphorylation events at the cell membrane and we engineer cells that display a kinase-dependent transmembrane signaling event in response to clustering of a chimeric receptor.  This work provides an example of the unique features that derive from biochemical reactions in non-uniform environments.

Plant power: The ultimate way to 'go green'

Photosynthetic organisms are able to use solar energy and carbon dioxide for the production of organic compounds. Based on initial formation and subsequent turn-over of carbohydrates, plants channel energy flux and carbon into specific biosynthetic pathways to optimize growth and development and adapts to abiotic and biotic environmental challenges by producing bioactive defense compounds. Several of these compounds are structurally complex and highly valuable pharmaceuticals used in the treatment of serious human diseases like cancer. Unfortunately such compounds are typically produced in small amounts by plants and sometimes also in plant species difficult to grow on a commercial scale. Most of the pathways responsible for the formation of the compounds involve cytochrome P450 catalyzed key steps difficult to copy using organic chemical synthesis. Using the “share-your- parts” principle of synthetic biology, we have now succeeded in breaking the evolutionary compartmentalization of energy generation and production of bioactive compounds. As proof-of-concept, we have relocated the entire P450 dependent pathway for the cyanogenic glucoside dhurrin to the chloroplast. The P450s were incorporated into the thylakoid membranes and shown to be driven by the reducing power generated by photosystem I with reduced ferredoxin as the direct electron donor to the P450s. Likewise, it was possible to directly incorporate P450s into the photosystem I reaction center complex by using some of the small subunits of this complex as membrane anchors instead of the native P450 anchors with the long term goal of building a supra-molecular enzyme complex catalysing light driven synthesis of pharmaceuticals and other interesting bioactive molecules. The production systems are being developed and optimised using transient expression in tobacco as the experimental system followed by stable transformation of cyanobacteria and moss strains grown in closed photobioreactors. Key target compounds are structurally complex diterpenoids.

Responsible Representation

In order to address the question of “Responsible Innovation” we have to ask in which ways Synthetic Biology is innovative in the first place: Are we looking at ways to responsibly redesign the biosphere, to responsibly bioengineer particular organismic structures? Or is SynBio innovative in how it shapes a new generation of researchers or in its adoption of new design processes or methods for knowledge production? The notion of “responsible representation” foregrounds intellectual honesty regarding the values and commitments that inform the adoption of research methods and research goals. If SynBio is defined mostly by its “innovative mind-set”, what is the cultural meaning of this mind-set and what are the associated questions of responsibility towards science, history, society, and the next generation of researchers? Among the examples to be discussed: What is the meaning of and how can one take responsibility for the Feynman-maxim “What I cannot create, I do not understand”?

Plants produce a tremendous array of natural products (many of which are specialised metabolites associated with particular species), including medicines, flavours, fragrances, pigments and insecticides.  The vast majority of this metabolic diversity is as yet untapped, despite its huge potential value for humankind.  So far, research into natural products for the development of drugs, antibiotics and other useful chemicals has tended to focus on microbes, where genome sequencing has revolutionised natural product discovery through mining for gene clusters for new metabolic pathways.  Identifying novel natural product pathways in plants is extremely difficult because plant genomes are much larger and more complex than those of microbes.  However, the recent discovery that genes for some types of plant natural product pathways are organised as physical clusters is now enabling systematic mining of plant genomes in the quest for new pathways and chemistries. Improved understanding of the genomic organization and regulation of different types of specialized metabolic pathways will shed light on the mechanisms underpinning pathway and genome evolution.  It will also open up unprecedented opportunities for exploiting Nature’s chemical toolkit.

The main purpose of synthetic biology is to develop basic biological functional modules, and through rational design, develop man-made biological systems that have predicted useful functions. In this talk, I will discuss two methods in rational design of functional biological circuits: the forward engineering and the reverse engineering. Both methods are proven to be successful in electronic engineering. I will use two synthetic biology researches that conducted in my laboratory at Peking University to illustrate the above principles. The first example is to use forward engineering design to synthesis “Pavlov bacteria” which can perform learning and recalling functions; The second example is to use reverse engineering design to synthesize a cell which has a semi-log dose-response to the environment. These works demonstrate that design principles in electronic engineering can be transplant into synthetic biology, but one should pay special attention to the difference between electronic engineering and biological engineering.

Public dialogues in synthetic biology and other areas of emerging science and technology have emphasised the need for researchers and those who fund them to think through and broadly deliberate on the ethical and wider implications of their research, in a way that influences how their area of science and technology develops. This has catalysed funding by the UK Research Councils that has led to the development a framework for responsible innovation which I will describe, as well as some experiments concerning how it might be implemented. I will argue the primary departure point for this framework is not ‘what are the risks?’ – important though this is – but ‘what sort of future do we want  synthetic biology to bring into the world?’ and ‘how should we collectively proceed under conditions of ignorance and uncertainty?’  Anchored in concepts of responsibility that emphasise care and responsiveness the framework will build on integrated dimensions of anticipation, deliberation and reflection as these relate to both the products and purposes of innovation that are hardly new: it is their coupling to responsiveness at personal, institutional and political levels that is important and is prompting new conversations on role and responsibility.

GMO environment risk assessment recently evolved to maturity. The five main steps were established and, within the first step (Context), the five crucial elements have also been defined. The step by step procedure successfully applies to every genetically modified organism. There are presently no reports on environmental damage due to GMOs, in spite of the diversity of constructions and widespread use, thus confirming the robustness of the systematic. Environment risks due to organisms having synthetic constructs replacing genes or gene fragments can certainly be evaluated in the same way,in spite of the lack of a suitable comparator for a fully new construct. Naturally, the evaluation of a fully new organism will be the greatest challenge, but is still far from the market. Therefore, it is important for the industry and for consumers to clearly establish to the society the power and appropriateness of the present risk assessment systematic when applied for the first generation of organisms based on synthetic biology, in order to allow their commercial release. In fact, the same groups against biotechnology are also against synthetic biology and they are trying to separate the risk assessment of products derived from the two technologies in order to build an almost unsurpassable barrier for the new technology. Moreover, international agreements and conventions, like the Cartagena Protocol to the Convention of Biodiversity, are by themselves, also powerful limitations to the adoption of new product based on synthetic biology. To avoid general frustration among young scientists devoted to synthetic biology, the transition from discovery to innovation should be discussed now, before the opposition blocks every future attempt by overprecautionary regulations. The talk will detailed discuss this subject.

Modelling the economy, creating the world

Modelling is a widely used practice within the study of markets and the economy. Recent studies suggest, however, that economic modelling is not merely a tool for representing an objective and external reality but rather operates as an instrument for intervening in the world. Economic models do not illustrate abstracted features of the economy: they fundamentally constitute its core. In this presentation, I will explore the uses of models in finance and economics, from how they define the course of nations, to how they constitute the fabric of financial markets. In doing so, I will explore a century of modelling practices, from the invention of national accounts in the early twentieth century to the dominance of algorithms and computer models in contemporary financial markets.

Programming languages for synthetic biological systems

Cells are the building blocks of life. If we could program living cells as effectively as we program digital computers we could make breakthroughs in medical treatment, sustainable agriculture and clean energy, while also better understanding how living systems compute. In spite of this potential there are still many challenges to overcome. Programming cells is highly complex and error-prone, and we are at a point where powerful computer software could significantly accelerate further progress. This talk presents ongoing work to develop computer languages for programming cells at three levels: molecular circuits, genetic devices and cell colonies. We present a language for programming molecular circuits made of DNA, and for characterising genetic parts that can be combined into devices for programming cell function.  Finally, we present software for simulating cell biofilms using 3D biophysical methods, which can be used to predict the effect of cell shape on colony morphology. Just as languages for programming digital computers heralded a new era of technology, languages for programming cells could enable new industries in biotechnology.

Synbio meets Conbio. Synthetic biology and responsibility to the natural world

The field of synthetic biology has just recently encountered the edges of the field of conservation biology (Conbio) and practitioners in both fields have yet to realize that there is much they should talk about. Conservation biologists are devoted to maintaining the variety and variability of life, often for its own sake. Synthetic biologists are interested in reducing variability to enhance performance for the sake of human ends. Conservationists are concerned about the increasing biotic homogenization of the world while synthetic biologists are interested in making hybrid organisms. So what responsibility does synthetic biology have towards the natural world from which it draws parts and inspiration, which will be affected by its creations, and in which its practitioners live? Are there wicked problems facing conservation that might be solved with the help of synbio? And what responsibility does conservation have towards organisms that are created by synthetic biologists? The time is ripe for an honest, broad conversation about human kind’s collective responsibility towards the natural world and the role that synthetic biology will play in its future.

Tools for large scale synthetic design and assembly

The successful assembly of multikilobase pieces of DNA requires very careful top down design and planning. GeneDesign can manipulate restriction enzyme recognition sites, change codon usage, and smooth out repetitive regions to ease the design process. It can also direct simple, automatable assembly of synthetic constructs with a simple protocol that minimizes PCR and stages the parallel, stepwise assembly of up to 15kb pieces. This protocol has no special requirements for sequence, making it ideal for the assembly of large constructs on the plasmid scale. 

For constructs on the chromosome scale, there is BioStudio. BioStudio is a framework for the multi-scale design of synthetic genomes. It can modify nucleotide sequences automatically or manually at multiple resolutions, using the GeneDesign libraries where appropriate. It can use the excellent, open-source, and user-friendly GBrowse as a GUI.  It is currently able to select recognition sites for the physical assembly of designed sequence, identify and incorporate unique sequences for PCR identification of wildtype and synthetic sequence, edit existing genome features, and create and annotate user-created genome features.  BioStudio annotates all changes to the genome sequence for version control, allowing the “roll-back” of any modifications with lethal phenotypes.  When coupled with a modular design strategy, versioning allows genome synthesis to proceed with as little re-synthesis as possible.

Intractable problems of tropical crops: an invitation to bring innovation from synthetic biology

 This is not an orthodox paper about research results presented at an orthodox scientific meeting.  It is an invitation to apply the  tools  of  synthetic  biology (SB) to solve some century-old problems of plant diseases in tropical crops that have proved intractable to solution by conventional tools  such as plant breeding or pesticides. Coconut Lethal Yellowing killing 90% of palms of susceptible varieties on Caribbean beaches;  frosty pod of cacao (chocolate) and  coffee rust,  which are  drastically affecting production and income in Central America;   Black Sigatoka disease of bananas where  30% of the costs of producing bananas is now due  to  pesticides used to fight the disease.  Formidable challenges are also incredible opportunities for change.  Humanity is embarking on a new powerful genomic revolution  and the field of SB offers the promise to revolutionize biological sciences and contribute to agriculture. Scientists can bring solutions. Policy makers must acknowledge both the SB’s potential and the public’s deep mistrust for new, untested technologies they feel are outside their control. The future success of SB depends to a large extent on whether public policy is well-crafted. Both groups  must work together to realize the potential.

One major target in Synthetic Biology is the creation of genetically modified organisms, to produce valuable chemical substances economically, in high yield and with low environmental impact, or to carry out beneficial chemical transformations. To create these organisms, it is often necessary to introduce a set of new genes and assemble them in specified positions within the organism’s genome. The genetic techniques currently available for this ‘assembly’ task are still inadequate, and gene assembly is considered to be a serious bottleneck in the work leading to the development of useful microorganisms. The first main aim of our research programme is to establish a sophisticated new methodology for this gene assembly process which will achieve a step- change in the speed and efficiency of creating new microorganism strains. For this purpose we have adapted a remarkable group of bacterial recombinases whose natural task is to carry out this kind of genetic rearrangement but which have hitherto been underused as tools for Synthetic Biology. We have designed rapid, robust and efficient ways of making gene cassettes that can be recombined in to specified positions in DNA. By doing this we can assemble collections of genes to order within a particular microorganism. Furthermore we can choose where to place the genes and in what order, and replace any individual parts with different versions. This permits much easier optimization of complex genetic systems than is currently possible. Using our new methods we intend to engineer microbial cells to make useful products e.g. next-generation biofuels, fine and platform chemicals.

Flybow, a genetic multicolor cell labeling approach to study neural circuits in Drosophila

Individual neuron subtypes have elaborate axonal and dendritic processes with characteristic shapes, reflective of their specific functions in neural circuits. Techniques that label single neurons within their complex environment are thus highly valuable additions to the neurobiologist’s toolbox. In 2007, Livet et al. developed the mouse Brainbow system, which enables the visualization of cells in multiple colors by the stochastic and combinatorial expression of three spectral variants of fluorescent proteins (FP). The Flybow system, which is based on the Brainbow-2 strategy, adapts this approach for use in Drosophila. It contains distinct features that take advantage of genetic techniques available in this model organism. Flybow transgenes are modular and combine modified DNA sequences from different organisms. These make it possible to induce recombination events and to drive expression of one of four membrane-anchored optimized FPs in any genetically accessible cell population of interest. Moreover, these features render the Flybow approach compatible with loss- and gain-of-function approaches. Using the fly visual system as an example, I will show how Flybow can support anatomical and functional studies of neuronal connectivity. Finally, I will discuss our current efforts in improving and expanding the functionality of our initial transgenes.

Unraveling principles of gene regulation using thousands of designed regulatory sequences

Genetic variation in non-coding regulatory regions accounts for a significant fraction of changes in gene expression among individuals from the same species. However, without a ‘regulatory code’ that informs us how DNA sequences determine expression levels, we cannot predict which sequence changes will affect expression, by how much, and by what mechanism. To address this challenge, we developed a high-throughput method for constructing libraries of thousands of fully designed regulatory sequences and measuring their expression levels in parallel, within a single experiment, and with an accuracy similar to that obtained when each sequence is constructed and measured individually. Using this ~1000-fold increase in the scale with which we can study the effect of sequence on expression, we designed and measured the expression of libraries in which the location, number, affinity and organization of different types of regulatory elements has been systematically perturbed. Our results provide several new insights into principles of gene regulation, bringing us closer towards a mechanistic and quantitative understanding of which how expression levels are encoded in DNA sequence.

Control Engineering Synthetic Biology

In this talk I will give a brief overview of some of the research activities in my group, the “Control Engineering Synthetic Biology” group, where we focus our efforts on developing foundational forward-engineering tools to mathematically model, and rigorously analyse, design and control synthetic gene circuits and cellular metabolism so as to endow engineered cells with novel functionalities. The tools and approaches that we take rely on principles drawn from Robust Optimal Control and Dynamical Systems theory, applied to Synthetic Biology problems.      

Some of the topics covered will include (if time allows): (a) Design of in vivo genetic feedback controllers for automatic robust regulation of branched and unbranched metabolic pathways, and (b) Exogenous data-based optimal feedback control of gene regulatory networks.      

(a) Among Synthetic Biology’s most prominent applications is the manipulation of bacterial metabolism for producing high-value chemicals in diverse sectors such as energy, biomedicine and food technology. In this regard, we are developing foundational tools for the analysis and design of feedback control synthetic biodevices that automatically regulate bacterial metabolism according to pre-defined objectives. Because these feedback controllers are intracellular, they have a great potential for applications where cellular behaviour needs to be controlled without real-time human intervention.       

(b) In the second part of the talk, I will present research results pertaining to the inference of (close-to) optimal feedback control strategies for exogenous control of biological systems (natural or synthetic) directly from input-output measurements, i.e., without the need for identifying a mathematical model of the system’s dynamics a priori. The examples discussed include data-based inference of optimal control strategies for regulation and reference trajectory tracking in synthetic gene regulatory networks such as the toggle-switch or the generalised repressilator.

Designing Biomaterials for Ultrasensitive Biosensing and Regenerative Medicine

Bio-responsive nanomaterials are of growing importance with potential applications including drug delivery, diagnostics and tissue engineering (1). A disagreeable side effect of longer life-spans is the failure of one part of the body – the knees, for example – before the body as a whole is ready to surrender. The search for replacement body parts has fuelled the highly interdisciplinary field of tissue engineering and regenerative medicine. This talk will describe our research on the design of new materials to direct stem cell differentiation for regenerative medicine (2). This talk will also provide an overview of our recent developments in the design of materials for ultrasensitive biosensing. Our recent simple conceptually novel approaches to real-time monitoring of protease, lipase and kinase enzyme action using modular peptide functionalized gold nanoparticles and quantum dots will be presented (3). Furthermore we have recently developed a new approach to ultrasensitive biosensing through plasmonic nanosensors with inverse sensitivity by means of enzyme-guided crystal growth (4) as well as a “Plasmonic ELISA” for the ultrasensitive detection of disease biomarkers with the naked eye (5). We are applying these biosensing approaches both in high throughput drug screening and to diagnose diseases ranging from cancer to global health applications.

Lotte Søgaard-Andersen obtained her M.D. and PhD in molecular biology from the University of Odense in Denmark. She moved to Marburg in 2004 as Director and Head of the Department of Ecophysiology at the Max Planck Institute for Terrestrial Microbiology.

Her research interests focuses on how bacterial cells process information to generate and regulate output responses such as adaptation, differentiation, growth and cell movement. Information processing is carried out by complex networks of signal transduction proteins. A challenging problem is to understand how these protein networks are organized in space and time to allow the ordered execution of these various tasks. We probe this question by studying signal transduction pathways and networks governing development, motility, cell polarity, and cell cycle in Myxococcus xanthus.

Defining a molecular module for regulation of dynamic cell polarity

All natural cells display regulated gene expression and are spatially highly organized. Major strides have been made in synthetic biology to design and engineer circuits that control gene expression. In comparison, the design and engineering of circuits for the spatial organization of cells remain a central challenge. This deficit is, at least in part, due to our poor understanding of the mechanisms responsible for spatially organizing cells. Bacterial cells display polarity with many proteins localizing asymmetrically to specific subcellular regions. Moreover, several of these proteins localize dynamically and change their localization over time. For most of these proteins, changes in localization are intimately tied in with cell cycle progression. A comparatively simpler case of bacterial cell polarity is represented by motility proteins in the rod-shaped cells of M. xanthus that localize dynamically to the cell poles in a cell cycle-independent manner, i.e. during a cellular reversal motility proteins localizing to the lagging cell pole switch to the new lagging cell pole and proteins at the old leading pole switch to the new leading cell pole. This system for cell cycle-independent regulation of dynamic cell polarity is built around the small GTPase MglA, which functions as a nucleotide-dependent molecular switch, and its cognate GAP MglB. MglA/GTP and MglB bind to the leading and lagging cell pole, respectively and define the leading/lagging polarity axis in M. xanthus. In response to signaling by the Frz chemosensory system, MglA/GTP and MglB switch poles resulting in an inversion of the polarity axis. We use this system to understand design rules for circuits regulating dynamic cell polarity. Our work to characterize the components of the system as well as our efforts to establish this system as a module for regulation of dynamic cell polarity in other bacteria will be presented.

Biological engineering problems require innovative DNA designs. Once a DNA design problem has been defined, crowd innovation can be harnessed to explore solutions. We proposed the problem of formaldehyde detoxification in Arabidopsis thaliana, based on known enzymatic pathways from other organisms. In GenoCon, the first international rational genomic design contest, contestants designed DNA to introduce these pathways by codon optimization and addition of various cellular localization tags. As a competition, GenoCon presents challenges for rational design of DNA sequences to enhance plant physiology, using public data, followed by outsourcing experimental synthesis and biological assays. Participants designed DNA sequences on our system: a web-based platform for sharing life science data along with a scripting interface for DNA design. Outsourcees of experiments synthesize the designed DNA sequences, transform the DNA into Arabidopsis thaliana, and assay the function: in this case growth tolerance to formaldehyde. We quantitatively analyze the growth in the presence of formaldehyde; this analytical process deeply depends on the expertise of the physiology of interest and requires collaboration among physiological specialists and informaticians. GenoCon also educates young scientists as genome design specialists, and as a web bioinformatics activity, no time consuming and expensive experiments are needed to participate. This first GenoCon challenge had 66 entries including eight high school students. The designs used three different synthetic pathways and varied the cellular location of each enzyme with protein localization tags directing to the chloroplasts, the mitochondria, and the endoplasmic reticulum. Five designs including two high school students were selected as finalists. We assayed the performance of the designs, and found several that displayed dramatic formaldehyde tolerance at intermediate formaldehyde levels.

Synthetic biology-based biohybrid materials for optically controlling mammalian cells

Plant and bacterial photoreceptors represent highly suitable tools for designing and constructing optically triggered switches for controlling genetic and biochemical processes in mammalian cells.  We will show how these tools can be used to control mammalian cell function, either by applying genetically encoded optical tools or by synthesizing light-responsive extracellular matrices. We will show the latest generation of multi-chromatic expression control technology for the differential activation of up to three genes by illumination with light of different color. Capitalizing on these light-triggered photoreceptors we will show approaches for synthesizing biohybrid materials that serve as light-controlled adjustable extracellular matrix for providing mechanical and biochemical cues to mammalian cells.  We will demonstrate how such synthetic biology-inspired biohybrid materials can be used for the remote-controlled administration of drugs at the example of one-injection-based vaccination regimes.

Synthetic biology provides the means of designing novel parts to aid in the controlled, tunable, and regulated expression of individual genes, circuits, and pathways.  Here, we describe recent advances in synthetic control of transcription by hybrid promoters in both Saccharomyces cerevisiae and the nonconventional yeast, Yarrowia lipolytica.  These synthetic promoters are comprised of two modular components—the enhancer element and the core promoter element.  We demonstrate that upstream activating sequences can serve as “synthetic transcriptional amplifiers” that can be used either individually or in tandem to tune and regulate gene expression.  By utilizing such an approach, we can create libraries with ranges of over 400 fold in mRNA level, create the strongest known constitutive promoters, and synthetically impart strength and regulation traits to promoter elements.  Second, we will discuss the synthetic design of expression cassettes and operons.  Importantly, we measure and model the impact of 5’ UTR regions on translational control to design synthetic cassettes that have sustained, high-level expression regardless of cloning strategy.  Finally, we discuss the impact of genetic context for synthetic parts—a particularly important aspect for characterization and predicable function.  By synthetically altering upstream regions, terminator components, and promoter structure, defined and reproducible function can be obtained.  Collectively, these results demonstrate novel approaches to synthetically alter and control gene transcription—a central goal of metabolic engineering and synthetic biology efforts.  Thus, we conclude with specific applications of these tools for metabolic pathway engineering.

KISS: K-plex Integrated Safety Switches

We propose a Gene Guard approach, “K-plex Integrated Safety Switches (KISS)”, rooted in the development of foundational genomic, regulatory and metabolic technologies. To demonstrate the generality of our approach and the prospect of extending safeguards to any microorganism, we present the coordinated development of KISS in both Escherichia coli and Saccharomyces cerevisiae, the best studied model prokaryote and eukaryote microorganisms, with natural and synthetic genomes. This combined approach assures the development of generic strategies for a wide range of microbes, and many aspects of it are even compatible with viruses. We designed five main KISS “SafeGuard Technologies” that act at the genetic, transcriptional, translational and metabolic levels, enabling us to deploy multiple GeneGuards for safety and isolation. By targeting different cellular processes in a multiplex fashion, our approach enables us to generically affect the function of one or more genes, nutrients or metabolites essential to microorganisms. Importantly, these SafeGuard Technologies can act individually or in any combination for multiplicative effectiveness. For example, engineered protein and/or RNA-based switches can be used to replace native regulatory mechanisms such that cell viability can be specifically linked to the presence of exogenous synthetic small molecules. Because any of hundreds of essential gene(s) can be re-engineered in this manner, we could increase the effectiveness of such a safety switch by multiplexing essential genes (e.g., histone genes in S. cerevisiae; guanylate and thymidylate kinase genes in E. coli and S. cerevisiae). The strong selections in place for essential gene function (viability) will allow assessment of the development of resistance to KISS to be rapidly assessed. If resistance is observed, mechanism(s) of resistance will be assessed. The nature of the design is such that it can readily be adapted to any microbe, multicellular organism or even viruses, any organism with one or more essential genes.

Logical Computation by Chimeric Antigen Receptors Increases Tumor-Targeting Capability of Engineered T Cells

T cells expressing tumor-targeting chimeric antigen receptors (CARs) have shown exciting promise in clinical trials, particularly in the treatment of B-cell leukemia. However, important challenges remain in the use of CAR-modified T cells, including off-target toxicity toward normal cells and susceptibility to mutational escape by targeted tumors. Due to a general lack of truly tumor-exclusive antigens, CARs typically target tumor-associated antigens that are also present on a subset of healthy cells, leading to on-target, off-tumor toxicity such as B-cell aplasia observed in patients treated with T cells expressing anti-CD19 CARs. Furthermore, patients who attain complete remission with anti-CD19 CAR-expressing T cells remain susceptible to relapse from the outgrowth of CD19- blast cells—i.e., mutational escape by tumor cells. One strategy to prevent mutation escape is to engineer CARs that recognize multiple antigen inputs and execute killing upon finding any one of the targeted antigens. Alternatively, CARs can be programmed to require the correct combination of input signals before triggering T-cell effector functions, thereby increasing targeting specificity. Here, we present an “OR-Gate” CAR that, when expressed in primary human T cells, efficiently lyse target cells expressing either CD19 or CD20, both of which are common markers of leukemic B cells. We demonstrate this dual-antigen targeting capability through quantitative measurements of target cell lysis and cytokine production. We will also present our designs for a “NOT-Gate” CAR and discuss its implications on our understanding of CAR signaling in relation to natural T-cell receptor signaling. Ongoing work focuses on widening the target differentiation response for the NOT-gate CAR and expanding the technology to additional antigen combinations for improved tumor-targeting specificity in T-cell immunotherapy.

Genome Engineering Technology for Synthetic Biology: a TALE and CRISPR Duet

The integration of genetic, biochemical, and engineering techniques and vast amount of data from genome sequencing have enabled us to synthesize various types of biomaterial for engineering purposes and utilize the genetic information of different biological systems and organisms with unprecedented resolution. However the emerging atlas for the development and application of synthetic biology and bioengineering is both illuminating and perplexing due to the lack of powerful and precise tools to control biological systems at genome-scale, especially in mammalian systems.

Recent developments in cell-specific perturbation technologies are beginning to give researchers the ability to reverse engineer various biological processes and probing the properties of specific molecules within a biological circuits or cellular ecosystems. Yet the need for a true easy-to-design, fast-to-synthesize, low-cost, multiplexable, open-source genome engineering technology still persists. Our work focuses on two parts to further advance synthetic biological tools to bridge this gap between data generation and experimental tools:

  1. developing and testing technologies to support large-scale high-throughput genome engineering efforts based on Transcription Activator-like Effectors (TALEs) and CRISPR-Cas systems and
  2. integrating these tools with a variety of readout methods for modeling biological processes and developing synthetic pathways and circuits for applications in a variety of organisms.

This transforming technology platform will likely improve our understanding and control of the complex biological pathways and circuits within both prokaryotic and eukaryotic systems, leading to potential new synthetic biology applications in basic biology and industrial-scale bioengineering, as well as advance the field of translational research by providing powerful tools to the research community for developing novel therapeutics to improve human health.

Repurposing the Peroxisome for Compartmentalizing Multi-Enzyme Pathways

Engineering high-flux metabolic pathways often results in undesired crosstalk with cellular factors of the production host.  These could be losses of metabolites to competing pathways, accumulation of toxic intermediates, allosteric regulation, protein degradation, and non-optimal enzyme activity at cytosolic pH or redox state.  We are following lessons from eukaryotic evolution to build a synthetic organelle capable of segregating engineered metabolism from the native biochemistry in the cytosol.  Towards this, we are repurposing the peroxisome as this organelle is not required for S. cerevisiae viability provided fatty acids are not used as a sole carbon source.  This organelle varies dramatically across fungi species with the majority of the cellular volume being occupied by the peroxisome in yeasts such as Hansenula polymorpha and methanol-induced Pichia pastoris, suggesting that higher capacity peroxisomes can be genetically engineered.  We have been able to improve the efficiency of a seldom-used targeting sequence that allows us to clear out the majority of the native luminal protein while importing multiple heterologous enzymes in the folded state.  Additionally, we have successfully implemented a strategy for redirecting plasma membrane transporters to the peroxisome membrane.  We are currently in the process of demonstrating that flux can be controlled through a branched pathway to control which product is synthesized.  Ultimately, we endeavor to alter the environment of this organelle (e.g., redox state, pH, etc.). to enable biochemistry that would not be feasible in the cytosol.

A highly specific synthetic metabolic pathway assembled from promiscuous enzymes

Synthetic biology aspires to construct novel metabolic pathways to useful, sometimes unnatural compounds. In extending natural pathways in novel directions, pathway engineers usually rely on the promiscuous activities (the ability to accept alternative substrates and/or synthesize alternative products) of recruited or mutated enzymes. However, the promiscuous enzymes that enable molecular discovery can generate hyperbranched pathways that preclude specific production of the target novel product. Here, we assembled a six-enzyme pathway in Escherichia coli for the 15-step synthesis of C50-astaxanthin, a non-natural purple carotenoid, by the judicious pairing of laboratory-engineered promiscuous enzymes. The initial combination of promiscuous enzymes encompassing the six desired biochemical functions resulted only in a mixture of non-target carotenoids. We then evolved variants of the first two pathway enzymes, isoprenyl diphosphate synthase (FDS) and carotenoid synthase (CrtM), with shifted specificity ranges. The combinatorial pairing of the selected variants resulted in specific production of C50 carotenoid backbones. The specific C50 backbone pathway enabled the directed evolution of the third enzyme, carotenoid desaturase (CrtI), to synthesize C50-lycopene. Coexpression of three downstream promiscuous enzymes (CrtY, CrtW and CrtZ) enabled the further extension of the C50 carotenoid pathway. The resultant pathway to C50-astaxanthin is both highly efficient and selective, despite containing not a single catalytically specific enzyme. We believe our results and analysis provide a framework for understanding how complex and precise biosynthetic networks can be built out of imperfect biosynthetic parts, either by synthetic biologists or natural evolution.

Composability of regulatory sequences controlling transcription and translation in E. coli.

The unpredictability of gene expression hinders our ability to engineer biological systems. A standardized library of well-characterized regulatory elements offers a potential solution only if such elements behave predictably when combined. To answer this question, we synthesized 27,000 combinations of common promoters, ribosome binding sites, and N-terminal coding sequences and simultaneously measured DNA, RNA, and protein levels from the entire library. Using a simple additive model, we found that RNA and protein expression were within 2x of predicted levels 80% and 64% of the time respectively. This large dataset allowed quantitation of global effects. Surprisingly, we found that the use of rare codons at the N-terminus strongly increases expression compared to common codons. Additionally, we measured how GC content and secondary structure affect translation efficiency and how translation rate alters mRNA stability. Even after accounting for the effects of these variables, unexplained severe outliers remain that hinder the use of prediction and standardization in large-scale genetic engineering projects. The ease and scale of our DNA synthesis approach indicates that it is feasible to design and screen large libraries for desired behavior.

Quantitative estimation of activity and quality for collections of functional genetic elements and definition of design principles for predictable gene expression.

The practice of engineering biology now depends on the ad hoc reuse of genetic elements whose precise activities vary across changing contexts. Methods are lacking for researchers to affordably coordinate the quantification and analysis of part performance across varied environments, as needed to identify, evaluate and improve problematic part types. We developed an easy-to-use analysis of variance (ANOVA) framework for quantifying the performance of genetic elements. For proof of concept, we assembled and analyzed combinations of prokaryotic transcription and translation initiation elements in Escherichia coli. We propose a new statistic, biomolecular part “quality,” for tracking quantitative variation in part performance across changing contexts. We used this metric to identify design flaws leading to unpredictable behavior, and motivate the engineering of improved genetic elements that can reliably express sequence distinct genes across a 1000-fold observed dynamic range and within 2-fold relative target expression windows with ~93% reliability. Lastly, we characterized a set of transcription terminators with widely variable efficiencies; used co-transcriptional folding simulations to identify context effects leading to deviant behavior; and developed a sequence-activity relationship model for this class of elements. In summary, we developed a gene expression control system comprised of transcription and translation initiation elements, and transcription terminators with predictable performance that enable reliable forward engineering of gene expression at genome scales.

Synthetic Biology in human stem cells: engineering our own building blocks

Induced pluripotent stem (iPS) cells have a tremendous potential for personalized and regenerative medicine, developing novel disease models or investigating the engineering rules of our own development. While the generation of such personalized stem cells became routine in the last years, it remains a challenge to precisely control their differentiation to specific cell types, tissues or organs. We have developed tools to rapidly construct and integrate site-specifically large gene circuits into stem cells where they measure protein and microRNA levels and direct their differentiation. In doing so we demonstrate generation of definitive endoderm, specific neural cell types and mesodermal derivates from human iPS cells. We propose that genetically engineering stem cells by applying principles from Synthetic Biology is a powerful emerging technology with a wide range of uses.

Tuning Receiver Characteristics in Bacterial Quorum Communication

Quorum communication is the process by which bacteria communicate, allowing them to modify the transcriptome in response to the nature and number of other bacteria in their environment. In Gram-positive bacteria, quorum communication commonly occurs via the production and sensing of small peptides by two-component systems, each of which consists of a membrane-bound response regulator and a protein kinase which triggers a phosphorylation relay leading to the activation or repression of suites of genes. The engineering of quorum communication systems permits synthetic biologists to manipulate the behaviour of entire populations of bacteria as well as that of individual cells.  In synthetic biology, as in electrical engineering, we need to be able to control the receiver response characteristics in order to ensure that the system of which they are part performs in a predictable, desired manner. In this work we apply computational design approaches, incorporating an evolutionary algorithm, to the modification of the receiver response characteristics of the SpaR/K two-component system of B. subtilis. This system produces and responds to subtilin, a lantibiotic produced by only some strains of the bacterium. The evolutionary algorithm builds simulateable models of the subtilin system using Standard Virtual Parts (SVPs), which can be swapped in and out of the model. The algorithms draws upon our extensive repository of SVPs: small SBML models of biological parts such as promoters, RBSs and CDSs. Both the kinetic parameters and the circuit topology can be modified. Manipulation of the subtilin system will allow us to control the behaviour of a mixed bacterial population. We demonstrate the application of our computational design system to the production of subtilin receiver response curves with a variety of shapes different from the sigmoid response of the wild type receiver.

Taming genome complexity via bacteriophage X174 synthetic genome design

Our capacity to read and write DNA has outpaced our ability to design useful and predictable DNA sequences. Synthesizing genomes could enable powerful new approaches to biological discovery, however, due to the overwhelming complexity of biological systems, most designs have largely recapitulated natural sequences. To advance synthetic genome design methods we focused on the 5.4 kb X174 bacteriophage genome because it is: (1) small enough to enable rapid prototyping of new designs, and (2) complex, displaying an intricate architecture encoding 11 overlapped genes spanning all reading frames. Two approaches were used to reduce the complexity of the X174 genome while addressing important biological questions. Gene overlaps are common in nearly every genome and their functional significance is controversial. We investigated the origin of gene overlaps by designing a fully decompressed synthetic genome ‘X174.1f’, that contained no overlapping genetic elements. We describe our genome design, construction, and successful redeployment. Phenotypic comparisons between wild type and X174.1f showed there were minimal observable differences between the two viruses, and no essential information in the gene overlaps. Additionally, the results suggest that gene decompression is a viable approach to reducing genome complexity. Secondly, we developed a method of genome simplification called ‘negative genomics’ that seeks to address a fundamental question of genome annotation: at what point can we confidently say we have found all the genes? To establish all potential open reading frames (ORFs), other than the 11 known genes, we searched the X174 genome using computational gene-finding tools. Finding 85 candidate cryptic ORFs we designed a new genome, called ‘X_clean’, with 88% of these cryptic ORFs erased via synonymous changes. Testing the prototype X_clean genome revealed that it is capable of forming plaques but is phenotypically different from wild type, suggesting previously undiscovered functions associated with the disrupted ORFs.

Bottom-up coarse-grained modelling approach to build an E. coli virtual cell for synthetic gene circuits engineering

Given an unprecedented ability to manipulate cells through synthetic biology to address problems in areas such as energy, health and environment, currently we still face challenges in perfecting an engineered system to our desire. The daunting challenges confronted by the biological circuit engineers are, complexity, unpredictability and variable behavior of the host system that contains the engineered designs. In addition, the practice of trial-and-error synthetic circuit designs and in vitro evaluation are laborious and time-consuming. Currently, models able to predict host-dependent circuit functions and burden on the host-cell environment accounting energy consumption, resource uptake and cellular processes are lacking. The insights from those models could be used to engineer and fine-tune the synthetic gene circuit’s components and parameters for optimal protein production and reduced host-burden effects. To this end, we propose a novel E. coli virtual cell for predicting the behavior of different synthetic biological devices in silico. The model incorporates three key ‘cellular processes’ and its components: (i) ‘nutrient uptake’ to evaluate energy compensation, (ii) ‘growth’ to determine macromolecular composition, pools of cellular machinery and monomer synthesis, and (iii) ‘replication’ of its components under regulation. Our preliminary results demonstrate that our model is able to reproduce the number and concentration of proteins, RNAs and cellular machineries of the host system at varying growth rates. We will present the development of this model considering how glucose as the sole energy source under regulation, a single virtual cell allocates energy and resources in synthesizing RNAs, proteins including machineries and monomers, initiation until completion of replication (doubling time) by monitoring growth rate and timing cellular processes. Looking forward, the work described here is a step towards predicting synthetic circuits behavior and its host-effects.

Synthetic Genetic Circuit for Diverse Enzyme Screening from Meta-genome

Large-scale screening of enzyme libraries is essential for the developments of cost-effective biological processes, which will be indispensable for the sustainable green chemistry. Here, we report a single cell based screening using a genetic circuit that enables the cell to respond quantitatively to aromatic molecules, which is released from substrates by the activity of target enzymes. The genetic circuit consists of two AND gates where the first one is turned on by a target enzyme and a substrate with an aromatic side chain. The aromatic molecule, in turn, could be an input signal of the second AND gate and it is turned ON by a sensor protein which initiates the transcription of a GFP fluorescent reporter gene after the recognition of aromatic molecules. We used a bacterial regulator, dmpR, as the phenol sensor protein which could be replaced by other effector binding genes such as tbuT if the effector is toluene. In cells harboring this genetic circuit, diverse enzyme activities, such as those of tyrosine phenol-lyase, lipase, cellulase, and methyl parathion hydrolase, were detected by the fluorescence emission when phenol- or nitrophenol-derivatized substrates of these enzymes were supplied. Along with these cells, a high throughput flow cytometry was successfully used to isolate a novel phosphatase from a metagenome library derived from tidal flat sediment using phenyl phosphate as a substrate. Our result shows that the genetic circuit provides a widely applicable tool for high throughput and quantitative screening of diverse activities from large-scale enzyme libraries. In addition, quantitative part characterization of the circuit by analyzing their fluorescence changes would provide useful information for further plug and play circuit design.

Engineering cell-based devices for design-driven medicine

The ability to engineer customized mammalian cellular functions would enable the construction of sophisticated cell-based therapeutics and transformative tools for fundamental biological research. Such capabilities could overcome persistent barriers to treatment in applications ranging from cancer immunotherapy to regenerative medicine. Synthetic biology provides such an approach for building novel cellular functions from the bottom up, and the “toolbox” of biological parts that operate in mammalian cells is rapidly expanding. To date, however, we lack the ability to construct synthetic cell-based biosensors that detect and respond to exclusively extracellular cues. Because many species of biological relevance, including cytokines, chemokines, cell-surface antigens, and many pathogens are exclusively extracellular, engineering cell-based devices that interface robustly with host physiology will require sensors for extracellular species. To address this need, we have developed a Modular Extracellular Sensor Architecture (MESA). By coupling cell surface sensing modalities to orthogonal intracellular signaling mechanisms, this platform enables the engineering of novel cellular functions such as multiparametric evaluation of extracellular cues. Finally, I will also discuss our application of these capabilities to probe interactions between cancer and the immune system, and to develop safe and effective therapies that harness the immune system to eradicate cancer.

Protein Cages as Templates for Nanoparticle Synthesis and Molecular Carriers

Synthesis of monodispersed nanoparticles that are free from aggregation is particularly challenging using chemical methods. E. coli has been engineered to synthesize iron nanoparticle by increasing the metal intracellular sequestration and production of protein cage as the biological template. The protein cages are formed by self-assembly of multiple subunits forming highly uniform hollow spherical cage structures of nanometer size. Expression of both the FeoB iron transporter and ferritin under inducible promoter results in the production of approximately 10 mg of protein cage/liter of culture; loaded with up to 200 Fe/cage forming an iron core of ~8 nm. This loading can be optimized in vitro with the highest loading observed at 7000 Fe/cage. Besides serving as template, the protein cages have been shown to assist the solubilization and prevent the aggregation of the nanoparticle. Further modifications of the protein cages allow tailoring of its function as carriers for therapeutic and diagnostic agents. Due to their proteinaceous nature, the protein cages allow facile modifications on its internal and external surfaces, as well as the subunit interfaces. Modifications on the internal and the external surfaces allow conjugation of small molecule drugs or contrast agent and targeting ligands, respectively. The subunit interaction is of special interest in engineering triggered release property onto the protein cage. Applications of these protein cages as molecular carrier with triggered release capability will also be described.

Universal computing device in mammalian cells based on orthogonal NOR genetic gates

Electronic computer circuits consist of a large number of connected logical gates of the same type, such as NOR or NAND, which can be easily fabricated and which can implement any logical function. In contrast, transcription factors as the biological mediators of the cellular logic act on the whole set of binding sites within each cell. The complexity of designable genetic regulatory circuits is therefore limited by the availability of orthogonal transcription factors. The diversity of modular TAL (transcription activator-like) DNA binding domains is almost limitless. Here, we introduce designed orthogonal NOR gates based on TAL repressors as the universal scalable logical functions. Binding site for the designed TAL repressors were positioned upstream of the promoter, which decoupled the effect of any particular sequence on the transcription level variability. We implemented all 16 two-input logical functions within mammalian cell from combinations of TAL repressor-based NOR gates. According to Alan Turing the universal computing machine must be able to accept as input data values as well as instructions that define which logical functions should be performed on those data values. We constructed a genetic logical circuit composed of NOR gates, where one input is used to select execution of either AND or OR function over the two data inputs, demonstrating the principle of an universal biological computation device in mammalian cells. Biological genetic networks employing orthogonal designed NOR gate can therefore be used to implement in principle any logical function within mammalian cells to engineer a complex cellular response.

Safeguarding synthetic biology: opportunities to influence international policy making

The SB community, throughout its history, has successfully engaged with the societal implications of their work. Efforts by the community have been much heralded and have been held up as an example to other scientists. Community work in addressing security concerns has received particular attention and yielded concrete results. Much has been accomplished but now is not the time for complacency. Security efforts could still unduly restrict the promise of SB. Modern approaches to biology also pose distinct challenges to traditional security approaches. Often overlooked, SB also provides new opportunities to counter deliberate disease and the misuse of the life sciences. This presentation explores, through specific examples, emerging risks to and from synthetic biology from the security sector as well as opportunities for addressing them.  Better balancing science and security interests will be a major theme of international policy and public discussions over coming years as focus on ‘Dual-Use Research of Concern’ expands from a limited set of influenza research projects to biology and biotechnology more broadly. This presentation reviews three relevant international process of particular importance to the SB community: the intersessional programme of the Biological Weapons Convention, focusing in particular on opportunities to influence international policy making; relevant work of the World Health Organization, including February 2013 meeting on Dual Use Research of Concern on Current Issues and Innovative Solutions; and the work of the Temporary Working Group on Convergence of Biology and Chemistry of the Scientific Advisory Board of the Organization to Prohibit Chemical Weapons.

Spanning high dimensional expression space using ribosome binding site combinatorics

Protein levels are a dominant factor shaping natural and synthetic biological systems. While proper functioning of metabolic pathways relies on precise control of enzyme levels, the experimental ability to balance the levels of many genes in parallel is a major outstanding challenge. Here, we introduce a rapid and modular method to span the expression space of several proteins in parallel. By combinatorially pairing genes with a compact set of ribosome binding sites we modulate protein abundance by several orders of magnitude. We demonstrate our strategy by using a synthetic operon containing fluorescent proteins to span a three-dimensional color space. Using the same approach we modulate a recombinant carotenoid biosynthesis pathway in E. coli to reveal a diversity of phenotypes, each characterized by a distinct carotenoid accumulation profile.  In a single combinatorial assembly we achieve a yield of the industrially valuable compound astaxanthin 4-fold higher than previously reported. The methodology presented here provides an efficient tool for exploring a high-dimensional expression space to locate desirable phenotypes.

In the Tabor lab, he has extensively characterized two bacterial light-sensing systems using the Light Tube Array (LTA), a custom apparatus which he designed and built. The LTA can generate up to 64 independently programmed light environments for cultures grown in a standard culture tube format.

This hardware solution enabled Evan to develop a standardized experimental workflow and to collect a large quantity of dynamical gene expression data. Using this data, he constructed quantitatively-predictive light-input/gene-expression-output models of both light-sensing systems. These models have enabled pre-computation of light programs which result in precise control of expression dynamics. Evan is now working to develop an optically-controllable continuous culture apparatus with fluorescence readouts which will enable long-timescale online control of light-sensing systems.

Multichannel Programmable Gene Expression Dynamics in E. coli using Engineered Optogenetic Signaling Pathways

We have utilized both the red/green-sensing CcaS/CcaR and red/dark-sensing Cph8/OmpR two component systems (TCSs) to achieve precise, quantitative control of gene expression dynamics in E. coli. First, we have constructed a programmable array of light emitting diodes (LEDs) that allows calibrated dosing of different colors of light in any desired temporal pattern in up to 64 standard tubes of growing cells. We demonstrate for each TCS that the application of different activating to inactivating light ratios allows us to set a desired analog gene expression level. By shining light ratios in a time-varying sequence, we can then drive cells to move between desired analog expression levels without adjusting the growth media. Gene expression is reported by fluorescent proteins and single-cell data is acquired from each culture via flow cytometry. Our observations of cells grown in a variety of time-varying light sequences are well described by a phenomenological model whose kinetics and steady-state levels are determined by the illumination intensities. After calibrating the parameters of the model for each system with a dataset of gene expression time-courses under a variety of illumination patterns, the model has successfully predicted light control sequences that drive each TCS to generate arbitrary gene expression time-courses including linear ramps, accelerated steady-state switching, and sine waves of varying amplitude and period. Furthermore, we have under development a dual-input system which allows for the simultaneous control of both TCSs. This level of quantitative, temporal control of gene expression would be extremely difficult to achieve with traditional modes of gene regulation. Utilizing optogenetic devices, researchers can more readily adapt well-developed approaches for system identification, characterization, and control to biological systems, helping to make biology more engineerable. Thus, as it has in neurobiology, the precise perturbative nature of optogenetic tools therefore stands to contribute significantly to systems and synthetic biology.

Sequence to Chassis in hours with a BotNet

Denovo assembly and annotation of genomes has historically required the resources of large genome centers, custom software pipelines and expensive dedicated compute clusters.  Taking advantage of advances in sequencing and software we have built an engineering oriented genome annotation pipeline with an emphasis on identifying standard parts that an engineer needs to rapidly engineer a new chassis.  We have substituted a peer to peer architecture and cloud computing for traditional, IT-intensive compute clusters.  The annotation process focuses on finding core canonical gene sets, flagging any species specific irregularities in those systems rather than characterizing the eccentricities of a specific organism.  Our goal is to generate a set of standard promoters, loci, pathway parts and codon usage patterns from raw next generation sequencing data within hours of DNA sequencing.  The output formats are tailored to work directly with our Genotype Specification Language (GSL). Coupled with a pathway design of interest we envisage a novice using GSL to translate a general pathway design into species specific parts within a day of sequencing a candidate microbial chassis

Bacto-engineering: from biopixels to cancer

Bacto-engineering: from biopixels to cancer In many respects, bacteria are an ideal design platform for synthetic biology. They are small, extremely hardy, inexpensive to maintain, reproduce quickly, and comprise a vast array of species with unique properties. An expanding future landscape of integrated synthetic biology will utilize the native networks of diverse microbial species in concert with our own engineered gene circuits. In this talk, I will primarily describe an LCD-like array of colony “biopixels” that collectively report the concentration of a target compound with a frequency-encoded signal[1]. These synchronous oscillations are maintained across populations as large as 13,000 colonies over centimeter length scales. Multi-scale coordination is achieved by layering 2 modes of communication – local quorum sensing and global redox signaling that utilizes the native aerobic response network. I will also describe several snapshots of recent work edging toward the clinical arena. We show that existing genetic circuits function equivalently in clinically-relevant hosts[2], and develop an experimental approach to study their in-vivo performance using mouse models of cancer[3, 4]. This platform is enabling work toward therapeutic applications, where we are engineering oral probiotics for instrument-free cancer diagnostics[5]. 1.    Prindle, A., et al., A sensing array of radically coupled genetic ‘biopixels’.

Engineering an Oral Therapeutic for Celiac Disease

The ability to rationally design enzymes to specifically combat certain diseases, such as celiac disease, has the potential for tremendous advances in medicine.  Celiac disease is characterized by intense abdominal pain, malnutrition, and serious illness in 1-2% of the population upon ingestion of dietary gluten.  The basis for this disease is an inflammatory immune response to incompletely digested gluten peptides in the intestine.  To combat celiac disease, we first identified an enzyme that demonstrates some of the desired properties for an oral therapeutic to treat this disease, and then used advanced computational protein design tools based on the Rosetta Molecular Modeling Suite to engineer the enzyme to harbor the properties that it was lacking.  The resulting enzyme, called KumaMax, will break down gluten in the stomach before it can elicit an immune response in the intestine.  KumaMax demonstrates all of the characteristics required as an oral therapeutic for celiac disease: stability and activity in the conditions of the human stomach, specificity for gluten protein, and easy production and purification methods.   This enzyme is capable of breaking down over 97% of an  immunogenic peptide derived from gluten in gastric conditions in less than an hour, demonstrating its potential for use as an oral enzyme therapeutic.

Reprogramming Animal Behavior by Artificial Modification of Neural Circuit Connections - Towards a Synthetic Neurobiology

The beautiful field of synthetic biology is successfully modifying, converting or plainly reinventing cellular and molecular processes, with the aim of improving our understanding of biology, and perhaps even improving biology. We wished to adopt the perspective and principles of synthetic biology to neuroscience, targeting neuronal connectivity rather than genetic interactions, and reprogramming whole animal behavior rather than cellular function. The fundamental building blocks of neural circuits underlying neuronal connectivity are synapses. In order to artificially modify synaptic connectivity we sought to introduce a new synapse between adjacent neurons in an existing neural circuit. However, inserting heterologous chemical synapses into a circuit would be difficult due to their enormous complexity and hundreds of constituent proteins. In contrast, electrical synapses, or gap junctions, consist of as little as one protein type. Moreover, the molecular constituents of vertebrate and invertebrate gap junctions belong to completely distinct protein families: connexins are exclusive to vertebrates and innexins to invertebrates. Importantly, while proteins from the same family can interact to form heterotypic gap junctions, no compatibility has been found between connexins and innexins. Thus, we reasoned that connexins expressed heterologously in neurons of the invertebrate nematode C. elegans would form gap junctions exclusively between themselves, and that these new connections could be used to modify existing connections in intact animals. We demonstrate that a genetically modified mammalian connexin gene can be functionally expressed in the C. elegans nervous system. Using this approach, we have been able to target the insertion of functional electrical synapses into existing inhibitory and excitatory chemical synaptic connections in the C. elegans olfactory circuit. We present data demonstrating their impact on neural transmission as well as whole animal behavior.

Photovoltaic Cells Engineered from Purple Membranes of Halophilic Bacteria and Quantum Dots

Engineering of photovoltaic cells based on the purple membranes (PMs) of the bacterium Halobacterium salinarum, containing photosensitive membrane protein bacteriorhodopsin (bR) is a challenging bioinspired nanotechnological goal. bR is an integral PM protein capable of transferring the physical energy of solar radiation into the chemical or mechanical energy. PMs possess unique physical, chemical, and dynamic stabilities, which guarantee stable and efficient biological functioning of bR and determines industrial applications of PMs. Here, we report on the development of photovoltaic cells based on oriented PM films, preparation of hybrid nano-biomaterial through controlled integration of semiconductor quantum dots (QDs) into PMs, and engineering of an advanced solar cell on the QD–PM hybrid material. This system has demonstrated enhanced solar energy harvesting and energy transfer, and improved photovoltaic properties due to the integration of QDs absorbing UV-solar solar light several orders of magnitude better than native bR. Moreover, Frster resonance energy transfer (FRET) from QDs to bR with an efficiency approaching 100% may be achieved via careful optical and chemical QD–PM coupling. In addition, the surface charge and functionality of QDs were varied to achieve the best QD integration. As a result, the solar photovoltaic cells based on dried oriented PMs (with and without QDs) were engineered, their properties were analyzed by absorption spectroscopy and laser picosecond fluorescent spectroscopy, and their current–voltage characteristics were measured. The results demonstrate a more than 10-fold increase in the rate of formation of the M412 intermediate in the bR photocycle for the PM–QD system compared with the system employing PMs alone. Thus, we have not only developed a bioinspired nano-biohybrid cell with advanced photovoltaic properties, but also demonstrated the possibility to control the biological function of a photosensitive protein’s by means of FRET from functional semiconductor nanocrystals.

Semi-synthetic minimal cells: from origin of life to synthetic biology

In recent years, we have proposed the concept of semi-synthetic minimal cells (SSMCs) (1,2). These are cell-like compartments, based on lipid vesicles (liposomes), filled with the minimal number of biochemical species in order to display living-like properties, like self-maintenance and self-reproduction. Born within the origin-of-life research, SSMCs are now an important pillar of synthetic biology. The SSMCs technology aims at constructing simple cell-like systems from molecular components, by a bottom-up approach, which complements the more traditional top-down one, typical of synthetic biology. The state-of-the-art of SSMCs research focuses on the production of proteins within such synthetic systems, but the ability of assembling compartmentalized systems is rapidly growing, and paves the way to interesting biotechnological applications. In this contribution, we will shortly introduce the concept of SSMCs, and summarize the most relevant results in the field, emphasizing both the scientific and the technological aspects. In addition, we will discuss in detail our recent investigation (3,4) on the remarkable and spontaneous self-organization of solutes and lipids to form a functional synthetic cell. This intriguing observation might be at the basis of the emergence of life on Earth and moreover can be further exploited to advance the technology of SSMCs. (1) Luisi et al. (2006).

Synbio, Global Health and Governance

First Author: Dr. Conor M.W. Douglas

Other Author: Dirk Stemerding

SynBio practices are being positioned to address major global health issues through advanced vaccine development, diagnostics, drug synthesis, and the detection and remediation of environmental toxins. Such research is –and stands to be-  growing in many parts of the globe, and to include ‘smaller players’ (i.e. iGEM, DIY-Bio), in part due to the particular features of standardization, abstraction, and modular open source parts. To be sure, SynBio is a global endeavour, it has potential for global health, but it will also require global governance. Our understanding of ‘governance’ is not unduly focussed on risks and other potentially negative implications. Instead we understand governance to be the set of institutions and practices involved in the inclusive steering of science and technology towards socially desirable outcomes. This paper reports on original social science research undertaken in project ‘Synthetic Biology for Human Health – Ethical and Legal Issues’ as a part of EU’s FP7 Science and Society program (www.sybhel.org). We report on a workshop we organized for global health experts, SynBio researchers, policy makers and others to identify the positives and productive policy and governance steps that would be needed to foster SynBio addressing major global health issues. Our work outlines the relationship between patent systems, institutional infrastructures, and global health improvements, and discuss some alternative incentive mechanisms for SynBio innovation in global health. We then shift to re-examine what positive and productive governance could mean for SynBio and global health by exploring the role of DIY-Bio and amateur communities, and how opening the research and development discourse in SynBio to various kinds of end-users could facilitate the global uptake and success of its products. Our conclusion suggests roles policy actors could play in fostering positive and productive governance, and the effects what a SynBio roadmap for global health could have in this regard.

Repurposing natural devices: engineering microbial pumps to secrete biofuels

The use of microbes to convert biomass to fuel is a promising technology, but the fuels are often toxic to genetically tractable microbial hosts, such as Escherichia coli, at industrially relevant levels. One promising solution to this challenge is to evolve multidrug resistance efflux pumps to secrete fuels from the cell, enabling increased fuel titers in addition to microbial tolerance. To that end, we have used directed evolution to engineer bacterial efflux pumps for enhanced tolerance to butanol. Using multiple rounds of directed evolution involving a selective growth competition method, we have isolated variants of the Escherichia coli AcrB efflux pump that enhance the growth of E. coli in the presence of n-butanol by approximately 25%. The growth enhancement is maintained even as the concentration of inhibitor is increased. Each variant is comprised of several mutations, and we have identified the single amino acid changes in AcrB that are responsible for the enhanced growth phenotype. Furthermore, expression of the variant pumps confers enhanced tolerance to isobutanol and straight-chain alcohols up to n-heptanol, but not chloramphenicol or geraniol. Significantly, we have also found that overexpressing these pumps in butanol production strains leads to increased titers of butanol.

Classification of synthetic biology patents and patent applications

In order to properly examine a patent application, the patent office first needs to determine the state of the art for the claimed invention. This is done through a search in collections of documents and databases of patent and non-patent literature. The huge collection of worldwide patent documents is systematically accessible by means of classification symbols. These classification symbols are assigned by the patent office to published patent applications and to patents and they are publicly available and searchable. The European Patent office (EPO) and the United States Patent and Trademark Office (USPTO) have together developed the Cooperative Patent Classification (CPC) system, which was launched on 1 January 2013 and which has the capacity to become the future international standard in patent classification. Classification relevant to the field of synthetic biology includes classification of proteins according to origin or function, classification of fusion proteins according to the function of their subunits and classification of expression systems according to their host cell. Patent classification can be used by the synthetic biology community to search the wealth of information present in patent databases. It also serves as an example of how a database of biological parts can be organized.

Programming Nucleic Acids Self-Assembly

I will discuss my lab’s research on engineering synthetic, nucleic acid-based nanostructures and applications in vitro and in vivo.  We have recently invented a general framework for programming the self-assembly of short synthetic nucleic acid strands into prescribed target shapes or demonstrating their prescribed dynamic behavior. Using short DNA strands, we have demonstrated the modular construction of sophisticated 2D  (Nature, 485:623-626, 2012) and 3D (Science, 338:1177-1183, 2012) structures on the 100-nanometer scale with nanometer precision. Using reconfigurable DNA hairpins, we have demonstrated diverse, dynamic behavior such as catalytic circuits, triggered assembly, and autonomous locomotion (Nature, 451:318, 2008).  By interfacing these synthetic, nucleic acid nanostructures with functional molecules, we are developing a diverse range of real-world applications. In biosensing, we have constructed robust and specific probes for detecting single-base changes in a single-stranded DNA/RNA target (Nat. Chem. 4:208-214, 2012). In bioimaging, we have engineered geometrically encoded fluorescent barcodes for highly multiplexed single-molecule imaging (Nat. Chem., 4:832-839, 2012). In nanofabrication, we have developed a versatile framework for producing inorganic materials (e.g. graphene [Nat.

I will discuss our ongoing work on developing RNA based scaffolds, conditional regulators, and computational modules to probe and program biology.
