Cytochrome P450s are best known for their role in drug metabolism in cells but are of growing interest as biocatalysts due to their ability to activate inert C-H bonds and catalyse selective oxidation reactions e.g. hydroxylation . P450s contain many flexible regions and undergo conformational change during catalysis. However, the effect of these changes on catalysis are poorly understood. To investigate, we will exploit cutting-edge biophysical approaches to trap individual enzymes in a nanoscale junction as a unique way to interrogate force stimuli (including mechanical forces) along crystallographic directions of the protein backbone. Precise electrical measurements of the single protein junctions4 will allow detection of single enzyme turnover and generate insight into the relationship between protein dynamics/conformational change and catalytic function.
This strongly interdisciplinary proposal combining chemistry, molecular biology, enzymology, and biophysics makes sense only when two supervisory teams covering the very different disciplines of the project join forces; the Díez-Pérez group is leader in the emerging field of BioMolecular Electronics and internationally recognized for its pioneering nanobiotech approach in single-protein electrical detection. The Barry group has extensive experience in discovery and characterisation of novel enzymes with emphasis in cytochrome P450s . The student should have a background in chemistry, biophysics, biochemistry or similar and will have the opportunity to work in an emerging field with important applications to biotechnology.
