  • Research Summary:

    My group is currently working on three general areas with the focus aimed at the elucidation of the mechanisms of novel enzymatic reactions and the design of methods to control and/or regulate their functions. Most of the biological systems under investigation are target candidates for therapeutic drugs.

    Enzyme Mechanism and Inhibitor Design: We study the mechanisms of enzymes involved in diverse biological processes including the formation of bacterial cell wall, biosynthesis of and resistance to antibiotics, and biosynthesis and metabolism of lipids.

    Metabolic Pathway Engineering: Through selective disruption and/or substitution of sugar biosynthetic genes in the microorganisms that produce bioactive glycosylated secondary metabolites, we are exploring the feasibility of engineering nature�s biosynthetic machinery for the production of novel compounds carrying designed sugar appendages.

    Protein Function Regulation: We study poly(ADP-ribose) polymerase, an enzyme that recognizes damaged DNA and turns on the repairing machinery through polyADP-ribosylation of itself and other nuclear proteins. This posttranslational modification is also essential to other crucial cellular events including apoptosis.
