CRYSTAL STRUCTURE OF HUMAN CYTOCHROME P450 3A4
OverviewOverview
Cytochromes P450 (P450s) metabolize a wide range of endogenous compounds, and xenobiotics, such as pollutants, environmental compounds, and drug, molecules. The microsomal, membrane-associated, P450 isoforms CYP3A4, CYP2D6, CYP2C9, CYP2C19, CYP2E1, and CYP1A2 are responsible for the, oxidative metabolism of more than 90% of marketed drugs. Cytochrome P450, 3A4 (CYP3A4) metabolizes more drug molecules than all other isoforms, combined. Here we report three crystal structures of CYP3A4: unliganded, bound to the inhibitor metyrapone, and bound to the substrate, progesterone. The structures revealed a surprisingly small active site, with little conformational change associated with the binding of either, compound. An unexpected peripheral binding site is identified, located, above a ... [(full description)]
