Introductory description

Much of bioscience is about discovery, i.e. learning about the naturally evolved properties of living systems. Synthetic and Engineering Biology adds a new dimension to our approach to the living world by identifying and characterizing cellular components (e.g. transcriptional elements such as promoters and transcription activators; mRNA elements such as untranslated regions or ribosome binding sites; protein domains that act as binding sites or conformational switches), and trying to assemble (engineer) these into new versions of (synthetic) biological systems. There are two major benefits to this approach. First, in the process of trying to engineer new biological systems, we improve our understanding of the naturally evolved biosphere (build-to-understand). Second, synthetic biology is in the process of radically enhancing our ability to create products and processes that are of value to human society (build-to-apply).
Synthetic biology is having a major impact on the development of applications in biotechnology, medicine, agriculture and energy, and accordingly brings academic and industrial interests together. We have therefore decided to incorporate contributions from representatives of some of our industrial partners into this module so that you can hear about commercially oriented research ‘first-hand’. Overall, this course will suit students who are interested in cutting edge science and who are keen to understand what the alternative (but related) paths of research in academia and industry might offer them in the future.

Module aims

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Core Principles of Synthetic Biology, an overview. • enabling technologies (DNA synthesis; rapid, large-scale assembly methods; modeling) • build to understand and build to apply; the design-construct-test-optimization cycle • the limits of the engineering paradigm in biology

Microbial cells as hosts for circuitry and pathways • circuitry designs in bacteria and yeasts; components extending from DNA through RNA to protein • predicted and actual behavior of engineered systems • experimental and computational tools available to characterize natural and engineered systems • cell-cell interactions, quorum sensing, microbial communities • applications of microbial engineered circuits, pathways and genomes in medicine, the environment, biotechnology

Computation modelling and tools. • The Design-Construct-Test-Optimise cycle (1 afternoon sessions) • in silico cloning • ODE modelling

Synthetic Biology of eukaryotic systems

• mammalian cell engineering – e.g. T cell engineering and medical applications • interspecies communication (molecular signaling between microbial and mammalian cells) • plant synthetic biology: synthetic sensors, metabolic pathways, genomes, with key examples related to food, biomass, biofuels, polymers, drugs.

Learning outcomes

By the end of the module, students should be able to:

• Understand the relationship between design, construction, testing and optimization in a biological context.
• Understand fundamental concepts of engineering biological systems
• Develop an understanding of the potential of synthetic biology to revolutionize the discovery process in biology and to enable step-change advances in biotechnology, medicine, food security and the environment
• Apply computational techniques and tools for designing synthetic biology systems
