Key Research Interests

My interests lie in the characterisation of enzymes that contain metal cofactors, principally enzymes involved in bacterial respiration. These include soluble cytoplasmic and periplasmic proteins, integral membrane proteins as well as extracellular membrane associated proteins that interact with the environment. In collaboration with colleagues in the Centre for Molecular and Structural Biochemistry, my research combines a broad range of biological, biochemical and biophysical techniques to explore protein-protein interactions, electron transfer between cofactors and the mechanism of enzyme catalysis.

Current Research Projects 

  • Electron transport in mineral respiring Shewanella
  • Interactions between outer membrane cytochromes and mineral surfaces
  • Reverse electron transfer (bioelectrosynthesis)
  • Biochemistry of periplasmic chaperones in Salmonella.

 

Life in our Research Group

The actions of bacteria have a profound effect on the global environment, from the cycling of greenhouse gases to the availability of minerals and nutrients in the soil. We are interested in how these processes work on a molecular level through the action of enzymes expressed by the bacteria. In order to study these enzymes we employ a broad variety of techniques across the breadth of the science faculty; from spectroscopic methods such as electron paramagnetic resonance in the Biophysical suite in Chemistry to the culturing of micro-organisms in the Wolfson Fermentation Suite in Biology. Our group is based in a well furnished laboratory on floor 2 of BIO, where we share laboratory space and equipment with Prof. Richardson, Dr. Bowater, Dr. Hemmings and Dr. Watmough.
