1. I have contributed to the following BBSRC grants (from their OASIS database):

Grant Reference: BB/M023877/1
Title: Fundamental membrane interactions of copper generated oligomers, profibrils and amyloid fibres
Institution of Grant: Queen Mary, University of London
PI, Viles J; co-PIs, Nield J (with Mark Baker, Lilia Milanesi and Matteo Palma)
Edited Abstract: There are a range of diseases including Mad-cow and Alzheimer's disease (AD) whose etiology involves proteins that self-associate into oligomers and amyloid fibers. It is this misassembly, of amyloid beta peptide (Ab), in the case of Alzheimer's disease, culminates in cell-death and dementia. Ab is a small peptide 40 or 42 amino acids long and there is strong evidence that oligomers of Ab42, but not Ab40, are the most cytotoxic. The effect of Cu-Ab-oligomers on liposome models of the bi-layer will facilitate the first 3D structures of lipid membrane disruption by oligomers.

Grant Reference: BB/R000514/1
Title: A cryo-electron microscope for structural and cell biology
Institution of Grant: Queen Mary, University of London
PI, Pickersgill, R; co-PIs, Nield J, and Vidya Chandran Darbari, Viji Draviam, James Garnett, Ewan Main, Lilia Milanesi, Conrad Mullineaux, Maxie Roessler, Alexander Ruban, Benjamin Stieglitz, John Viles
Edited Abstract: Advances in detector technology and image analysis algorithms have made cryo-EM the structural method of choice for large macromolecular complexes especially those with intrinsic dynamic properties and those available in only small quantities. With cryo-EM 100-1000 times lower protein concentration may be used as compared to X-ray crystallography one does not have to lock complexes into a single conformation. Each particle is imaged individually and may be sorted in silico according to their conformation, with research extended using cryo-tomography.

Title: Molecular basis of FtsH function in the cyanobacterium Synechocystis PCC 6803
Institution of Grant: Queen Mary, University of London
PI, Nield J
Edited Abstract: FtsH proteases, which are members of the AAA+ (for ATPase associated with various cellular activities) superfamily of proteins, play an important physiological role in the cyanobacterium, Synechocystis 6803, including the acclimation to various type of abiotic stress (e.g., light, heat and salt stress). A wide-ranging investigation into the structure and function of the four FtsH homologues found in Synechocystis 6803 will be conducted.

Title: A high-throughput crystallisation facility for protein structure determination
Institution of Grant: Imperial College London
PI, Hohenester, E; co-PIs, Nield J, and Geoffrey Baldwin, James Barber, Peter Brick, Katherine Brown, Martin Buck, Elisabeth Carpenter, Naomi Chayen, Stephen Curry, Paul Freemont, So Iwata, Stephen Matthews, Silvia Onesti, Robert Weinzierl, Xiaodong Zhang
Conclusions: This application provided for a robotic nanolitre protein crystallisation facility for the Centre for Structural Biology (CSB) at Imperial College London. The CSB is a college centre with affiliated groups from three faculties and provides both expertise and managed core facilities in all major techniques of macromolecular structure determination: X-ray crystallography, nuclear magnetic resonance spectroscopy, and electron microscopy. Robotic crystallisation has become essential to make progress in the emerging area of system-wide structural biology.

Title: Using
C. reinhardtii as a model system for determining the macromolecular structure of PSI and PSII by high resolution electron microscopy
Institution of Grant: Imperial College London
PI, Nield J; co-PI, Barber J
Conclusions: The transformable green alga,
C. reinhardtii, was used as a model system to obtain structural information about the macromolecular organisation of photosystem I (PSI) and photosystem II (PSII), in higher plants and other photosynthetic eukaryotic organisms that contain chlorophyll a/b light harvesting complexes (LHC) using electron cryo-microscopy and single particle analysis. Related studies were conducted to isolate and characterise a novel LHCI-PSI supercomplex, by negative stain electron microscopy (EM).

Title: Elucidating the structure of photosystem two by cryoelectron microscopy and single particle analyses
Institution of grant: Imperial College London
PI: Barber J; co-PIs Nield J and Van Heel M
Conclusions: This programme obtained a 3D structure of photosystem II (PSII) from spinach at 1.7 nm resolution using cryo-electron microscopy and single particle analyses. In addition, a 3D structure of the LHCII-PSII supercomplex from
C. reinhardtii was determined. All structures obtained were analysed in order to highlight similarities and differences with their 3D maps used as frameworks for incorporating structures of various subunits and subcomplexes obtained from X-ray and electron crystallography.

Title: Structure determination of a multi-subunit supercomplex of photosystem II by single particle analysis of cryo-electron micrographs
Institution of grant: Imperial College London
PI: Barber J; co-PI: Van Heel M
Post-doctoral researcher: Nield J
Conclusions: New and powerful techniques in the image processing of single particles from cryo-electron microscopy were used to reconstruct a 3D map of the multi-subunit supercomplex, photosystem II. This map was used to determine the position of subunits of this protein complex in order to understand the structural information obtained in the context of energy transfer, charge separation and water splitting.
