Research Profile

My research mostly involves studies of protein structure-function relationships and protein modification. Since proteins are involved in virtually every biological process, projects in this area can address a very wide range of biological questions. Current projects in my laboratory, many shared with academic colleagues, include studies on several groups of enzymes: the purple acid phosphatases (these contain an interesting binuclear metal catalytic centre); purine phosphoribosyltransferases (purine salvage enzymes which are potential targets for anti-malarial drugs); proteases and other proteins present in the venom of Australian snakes. I am also very interested in the covalent modification of body proteins by reactive drug metabolites, such as acetaldehyde, the major product of ingested ethanol. Our interest lies mainly in the question of how these modified proteins are involved in the pathology of alcohol abuse.These projects involve major techniques of biochemistry and molecular biology including recombinant DNA technology, bioinformatics, protein purification and structure determination.
