Title :

EPR and the Binding of Molecules to Cytochrome P450 Enzymes

Abstract :

The cytochromes P450 are a large enzymes superfamily found in every branch of life. Some isoforms help synthesize essential compounds and  are attractive targets for antibiotics. Other isoforms metabolize many pharmaceutical drugs and are one source of drug interactions. Many drugs directly bind heme in the active site but our pulsed EPR studies show a new binding mode with a water as a bridge between heme and drug, sometimes retaining enzymatic activity
