Education & Background

Ph.D., Birkbeck College, University of London, 1989

Research Description

Would you like to see biochemistry in motion? To learn exactly how enzymes accelerate and control chemistry at the molecular level? My primary interest is to understand the mechanisms of post-translational modification required for protein enzyme activity. Post-translational modifications of proteins, such as phosphorylation and glycosylation, are well known modulators of signaling pathways and molecular/cellular recognition. Only in the last few decades has their wide-spread role in generating novel catalytic cofactors within enzyme active sites been appreciated.

The principle tool of my research is macromolecular X-ray crystallography in combination with spectroscopic techniques both in the crystal and solution, kinetics and mass spectrometry. My approach has been to freeze trap catalytic intermediates in the crystal, leading to "snapshots" along the reaction pathway. These are then assembled into a "movie of catalysis" at the molecular level.

Additionally my lab is also interested in the use of microbial enzymes in bioremediation (removal of pollutants from the environment using biological organisms) and biofuel production (microbial production of energy-rich hydrocarbons as replacement fuels).
