Centre for structural analysis of complex biological systems

Lead Research Organisation: University of Bristol
Department Name: Biochemistry


Understanding the function of the molecules of life requires knowledge of their three dimensional structures. Seeing, at or near to the level of individual atoms, how the building blocks of life (proteins and DNA) are assembled enables us to understand both how they may act to drive the chemical reactions that power and maintain living cells, and how they are organised into more complex structures that form the basis of cells and tissues. Detailed knowledge of structure can explain how specific alterations affect function, for example where changes to specific molecules are linked to disease, or how biological systems can be engineered to fulfil useful functions, such as making new drugs or turning carbon dioxide into liquid fuels.

Most structures of biological molecules are derived from experiments where ordered crystals of the pure material are exposed to X-rays. The success of this approach relies upon inducing crystals to form. Unfortunately, for many interesting and important biological molecules this remains very difficult, and large numbers of experiments must be conducted to identify suitable conditions for crystal formation. However, recent technological developments have increased the number of experiments possible with limited amounts of material, and created automated systems to monitor the progress of experiments and detect crystals as they form. Furthermore, technology has improved our ability to create conditions mimicking those existing inside biological membranes (the structures that separate the cell interior from its surroundings and organise the cell into compartments) greatly simplifying the process of obtaining crystals of proteins that are normally associated with membranes. Such proteins perform key biological functions at the cell surface, enabling cells to recognise one another and to bind biological surfaces, and regulating the traffic of molecules, including other proteins, into and out of the cell. However, membrane proteins are much harder to work with, and hence less well understood, than other protein systems.

Here we request funds to purchase equipment that will transform our ability to grow crystals, and obtain structures, of a range of biologically interesting but technically challenging targets. We will create a state-of-the-art Facility to exploit recent successes producing proteins and protein assemblies in the quantities necessary for crystallisation. Specifically, we wish to purchase: i) a robot to set up crystallisation experiments in conditions replicating the membrane environment; ii) an automated system to house the numbers of crystallisation experiments made possible by robotic systems working on small scales, and that will monitor their progress without human intervention; and iii) a complete crystallisation facility, including a robot to set up experiments and a microscope to inspect the results, maintained in a controlled, oxygen-free, environment. We will use this equipment to obtain structures of a number of biological molecules and assemblies including: the machinery controlling protein movement across membranes; the surface proteins of the human red blood cell that determine blood group, surface proteins from disease-causing bacteria that enable them to bind human cells; giant molecular machines synthesising drugs and antibiotics; the protein assembly by which cells carry out the instructions contained within genes; artificial proteins that carry electrons; and a wide range of proteins, involved in processes from bacterial antibiotic resistance to conversion of carbon dioxide into liquid fuels, that only function when oxygen is absent. Through our strong links to other local Universities our Facility, which will be unique within the region, will be open to researchers across the South West and South Wales, and will provide cutting edge instrumentation on which to provide the next generation of scientists with skills essential to the UK science and technology base.

Technical Summary

High-resolution structural information can transform our understanding of a given biological system. X-ray diffraction remains the technique with the broadest application to diverse biological targets. Advances in instrumentation at all stages of the macromolecular crystallography pipeline, from protein expression to software tools, have greatly expanded the range of targets that may be considered amenable to structure determination. In this application we seek support to equip a Facility with instrumentation to enable crystallisation of a range of challenging structural targets of high scientific value, including soluble and membrane protein complexes, de novo designed protein systems and oxygen-sensitive enzymes. We request funding for i) a lipidic cubic phase (LCP)-capable robot for crystallisation of membrane proteins and complexes; ii) an automated crystal incubation and imaging system able to maintain and monitor large numbers of experiments, with capability for fluorescence detection of protein crystals and microcrystals in conditions of high background (LCP) and iii) a dedicated anaerobic chamber housing a crystallisation robot and microscope, together with a port for crystal freezing, for crystallisation of oxygen-sensitive systems. Our targets include membrane protein complexes from pro- (protein export; bacterial surface protein) and eukaryotic (erythrocyte membrane proteins) sources, polyketide synthase and eukaryotic transcription super-complexes, de novo designed membrane channel and oxidoreductase systems and a range of radical and redox enzymes. The Facility will enable us to fully exploit recent progress generating material suitable for crystallisation and augment existing capabilities for recombinant protein production and characterisation. No similar equipment is installed in the South West, while our strong local links in structural biology and graduate student training will enable this to operate as a regional Facility with a wide user base.

Planned Impact

This proposed Centre will deliver a major new resource for structural biology, advancing our understanding of complex biological systems necessary for medical intervention and their modification and exploitation, which will contribute substantially to the UK's global leadership in these areas. The Centre will progress and diversify such studies, focusing on significant biological challenges that fit with the BBSRC World-Class Bioscience strategy. Moreover the Centre will impact upon important strategic areas of Synthetic Biology and Nanotechnology, by providing new high-resolution information of protein components and complex systems.

We intend that this research will impact upon policy-makers, funding bodies and academic institutions by providing clear evidence of the value of state-of-the-art equipment and fundamental, interdisciplinary research for the future of UK science and education. In order to deliver this impact we will highlight the importance of scientific knowledge in maintaining and increasing the UK's leading position in higher education, emphasising the central role of science in educating the public as well as in schools and lifelong learning. We will also continue to promote such research outside the University, in the South West, nationally and internationally, and discuss potential impact with colleagues, other institutions, funding bodies and learned societies. Moreover by increasing knowledge of basic science the Centre will have a major impact on interdisciplinary training of early-career researchers. Additionally it will facilitate outreach opportunities to educate the public and about the importance of scientific discovery and to inspire young students, revealing the intellectual benefits of a career in bioscience.

The Centre will also foster new projects and collaborations at Bristol and beyond, as well as providing a resource for researchers throughout the UK. It will also provide a hub for workshops and practical courses.

The main areas of impact will be:
a) Delivering a state-of-the-art facility for biological structure determination of complex biological systems, establishing a unique resource in the UK and enabling new collaborations and training opportunities.
b) Delivering scientifically literate people to society. School pupils, undergraduates, postgraduates and early career researchers.
c) Engaging in science festivals, schools visits, talks, debates and press briefings. School pupils have been very effectively involved to date, as have the public; we also plan to formulate new strategies to widen the impact.
d) In the longer term, realising impact in drug development, energy security and synthetic biology.
Description The award has led to the establishment of a University facility for the structural characterisation of oxygen sensitive proteins, which is now enabling fundamental insights into biocatalysis, antimicrobial resistance and de novo redox protein design. In addition, the imaging facilities are being used across the University to support research efforts in the study, design and exploitation of proteins, including a number of projects performed in collaboration with industry and in particular with collaborators in pharma. Multiple high-profile papers are soon to emerge thanks to this investment.

These facilities have proven instrumental in advancing structural analysis of de novo designed proteins (Woolfson & Brady labs). This has lead to substantial major advances including introducing enzymatic activity in a completely de novo heptad-barrel protein (Burton et al., Nature Chemistry 2016 DOI:10.1038/nchem.2555), rational design and assembly of a range of oligomeric and water-soluble alpha-helical barrels that form channels (Thompson et al, Science 2014 Vol 346:485-488 DOI: 10.1126/science.1257452) and self-assembling peptide-based nanotubes (Burgess et al, Journal of the American Chemical Society 2015 137 (33) pp 10554-10562 DOI: 10.1021/jacs.5b03973). These studies have all relied on detailed crystallographic structures which have only proven possible to obtain with the advanced crystallisation facilities provided from this grant.

The Anderson lab have deployed the anaerobic crystallisation facility in a study to identify and structurally characterise reactive intermediates in heme enzyme-catalysed carbene transfer reactions, where simple olefins are cyclopropanated using ethyldiazoacetate and ferrous hemoproteins. We have focussed initially on the crystallisation of several natural and engineered enzymes (horse heart myoglobin and an engineered variant of P450 BM3) in their reduced, air sensitive states. In an alternative approach, we have also crystallised in the air stable ferric forms and soaked with reductant in crystallo. The crystals of reduced hemoprotein are then soaked with ethyldiazoacetate and rapidly frozen in liquid nitrogen for subsequent X-ray data collection at Diamond Light Source. We hope this will provide a significant insight into the mechanism of this valuable abiological chemistry.

Recent work from the Anderson group has culminated in the following output:

The de novo design of simplified porphyrin-binding helical bundles is a versatile approach for the construction of valuable biomolecular tools to both understand and enhance protein functions such as electron transfer, oxygen binding and catalysis. However, the methods utilised to design such proteins by packing hydrophobic side chains into a buried binding pocket for ligands such as heme have typically created highly flexible, molten globule-like structures, which are not amenable to structural determination, hindering precise engineering of subsequent designs. Here we report the crystal structure of a de novo two-heme binding "maquette" protein, 4D2, derived from the previously designed D2 peptide, offering new opportunities for computational design and re-engineering. The 4D2 structure was used as a basis to create a range of heme binding proteins which retain the architecture and stability of the initial crystal structure. A well-structured single-heme binding variant was constructed by computational sequence redesign of the hydrophobic protein core, assessed by NMR, and utilised for experimental validation of computational redox prediction and design. The structure was also extended into a four-heme binding helical bundle resembling a molecular wire. Despite a molecular weight of only 24kDa, imaging by CryoEM illustrated a remarkable level of detail in this structure, indicating the positioning of both the secondary structure and the heme cofactors. The design and determination of atomic-level resolution in such de novo proteins is an invaluable resource for the continued development of novel and functional protein tools.

The high-throughput crystallization equipment was instrumental in the Berger lab to crystallize TBP associated factor (TAF) 2, a cornerstone of the super-complex that regulates the transcription initiation of all protein encoding genes in euakryotes. Initial hits resulted in crystals that already diffract synchrotron radiation to better than 4 Angstroem resolution. The facilities has help in getting optimized crystal diffracting to 2.4 Angstroem resolution. Structure determination is in progress.
Facilities have also been key in obtaining crystals of an oocyte specific transcription factor TBPL2, which diffracted to 2 Angstroem resolution. The structure was solved and coordinates have been deposited (PDB ID- 6TH9); the corresponding publication is about to be submitted.

Using these facilities, Berger lab have also obtained crystals of an engineered Crown Domain from ADDomer; a synthetic self-assembling platform for highly efficient vaccination. Crystals diffracted to 3 Angstroem resolution at diamond light source. Structure determination is in progress.

In the Collinson lab the centre has facilitated new projects for the structural analysis of a number of different proteins relevant to protein secretion, membrane protein insertion and the mechanism of bacterial antibiotic resistance. This work continues.

The Spencer group has solved a protein structures in anaerobic conditions using the crystallization set-up in the oxygen free glove box. They are not yet published; pdb ID 6FZ6.

Exploitation Route This facility is now in integral part of BrisSynBio equipment suite, which will help sustain and update the centre for structural analysis in Bristol.

The fully functional and future proofed facility is now available to all structural biologists at Bristol for FREE. So, we now anticipate that it will this access will bolster structural biology at Bristol and increase our capabilities for protein structure determination. This is more relevant now than ever. We have secured the funds from the Wellcome Trust and from GW4 partners the £2.5M to establish high resolution electron microscopy and BBSRC funded computer cluster for image processing (BB/R000484/1 BlueCryo Image Processing Computing Cluster). The combination of electron microscopy of large molecular assemblies with X-ray crystallography of individual components and sub-assemblies will prove very powerful indeed.
