My research focuses on the Cytochrome P450 (CYP) enzyme superfamily. I use molecular dynamics computer simulations to explore three stages of CYP catalysis: the binding process, the chemical reactions involved, and the release of product. CYPs catalyze the oxidation of xenobiotic compounds, e.g., drugs, and thus play an important role in drug metabolism. CYPs rely on the heme-cofactor for their catalytic activity. Classes of CYPs exhibit different substrate selectivities and product regioselectivities even though the classes share a nearly identical heme complex. Understanding the CYP catalysis mechanism can help predict unwanted drug adverse effects in the early stage of drug discovery.
