Research Summary

Understanding of important enzyme-catalysed reactions, using a combination of the following techniques: synthesis of enzymatic substrates and inhibitors, isotope labelling experiments, enzyme purification and enzyme kinetics. Major areas of interest are enzymes involved in the bacterial degradation of aromatic compounds, and enzymes involved in bacterial cell wall peptidoglycan biosynthesis, as targets for the development of novel antibacterial agents.
