First of all thank you to everyone who has contributed to the exciting conference programme, which represents the breadth and depth of research and expertise across the Network. We hope that the programme, together with the poster sessions, will provide a real insight into some of the work already going on in the Network, and highlight some of the areas that are ripe for collaboration. Indeed, our overall objective is to foster communication and collaborations across the Network, but, of course, whether this happens is ultimately up to you. We are also very pleased to welcome the PIs of three other BBSRC/EPSRC-funded Networks in Synthetic Biology. They will be taking part in the panel Q&A session on Wednesday evening. The aim here is not to define what synthetic biology is, but to explore what people understand by it more broadly. We hope you will use this session to find out about how the other Networks view Synthetic Biology, learn something of the projects that are underway in them, and to explore opportunities for wider collaborations. Because new interactions and exploring potential collaborations are key, we have left plenty of time for networking and discussion over lunches, dinner, poster sessions, and in the bar! Finally, your feedback on how this meeting goes, and how it might be improved in future will be very welcome. Please give this to us, to Kathleen Sedgley directly, or use the tear-out form at the end of this programme. We hope you enjoy this first Annual Conference and the scientific and social interactions that it fosters. Best wishes, Dek Woolfson and Jonathan Rossiter 2 SCN Annual Conference, 23rd – 24th September 2009 Contents Table of Contents Welcome from Dek 2 Programme 4 Session 1: Components and self-assembly 6 Session 2: Encapsulation 11 Session 3: ELSI 15 Session 4: Responsive materials and movement 16 Session 5: Public engagement 19 Session 6: Towards systems 20 Panel Q&A session: What is Synthetic Biology and who cares? 25 Poster session PIs 29 PhDs and PDRAs 34 Delegate list 44 Thank you 46 Researcher exchange form 47 Feedback form 49 Maps 51 3 SCN Annual Conference, 23rd – 24th September 2009 Programme Programme ------------------------------------------------------------------------------------------------------------------ WEDNESDAY 23RD ------------------------------------------------------------------------------------------------------------------ 09-30 – 10-20 Arrivals and coffee 10-20 – 10-30 Welcome Dek Woolfson, Bristol Session 1: Components and self-assembly Chair: Louise Serpell, Sussex 10-30 – 11-00 William Taylor, NIMR Stick models of proteins 11-00 – 11-30 Andrew Turberfield, Oxford DNA nanostructures and molecular machinery 11-30 – 11-50 Karen Marshall, Sussex Structures of amyloid-like fibres and crystals formed from a self-assembling peptide 11-50 – 12-10 James Arpino, Cardiff Engineering allosteric control over GFP fluorescence 12-10 – 12-30 Craig Armstrong, Bristol Peptide components for Synthetic Biology 12-30 – 14-00 Lunch Session 2: Encapsulation Chair: Andrew Turberfield, Oxford 14-00 – 14-30 Steve Evans, Leeds Encapsulation: lipid membranes 14-30 – 15-00 Hagan Bayley, Oxford Engineered protein pores as components of soft micromachines 15-00 – 15-20 Nikolaos Daskalakis, Leeds Generating proton-motive force in probe-loaded vesicles 15-20 – 15-40 Jon Howse, Sheffield Vesicles by design 15-40 – 17-00 Posters Tea Session 3: ELSI ELSI research in SynBio: What’s being done?

We use of a secondary structure lattice based on regular layers of secondary structure to overcome this problem. or decoy models, the structure is built directly from the lattice and so their fold is predefined. For known structures, the ideal lattice must be matched to the structure and although this step might appear susceptible to marginal effects, we do not rely on a single best fit but retain all good fits to different lattice cores. This does not provide a unique definition of a protein fold but a match to any of the variations counts as a hit, giving a ``fail-safe'' position towards matching known folds. These predefined fold definitions can be encoded as simple string of text (called a topology string), and there is no ambiguity in whether a pair of folds are the same as they will either have identical strings or strings that contain mismatches. This approach avoids the problems encountered using RMSD-based measures associated with length differences and statistical significance. We used the more familiar RMSD measures as an extensive cross-check on our topological measure and it was clear that it could not distinguish many distinct topological changes against the background 'noise' associated with secondary structure shifts and loop variation. This level of protein structure analysis has been used in the prediction of protein structure as well as the classification of structure. Most recently these two studies have been combined in an analysis of the folds generated during structure prediction. Of the many thousands of distinct folds constructed, only one-in-ten were found to exist among the known structure. The remainder have been likened to cosmological dark matter.

I shall describe our recent work on self-assembled molecular structures and on molecular machinery, including the free-running bipedal molecular motor shown above, which is a chemically fuelled Brownian ratchet inspired by kinesin.
