The microsomal O-deethylation of a novel coumarin analog, 7-ethoxy-4-trifluoromethylcoumarin (EFC), to a fluorescent product was characterized. Results indicate that this analog provides a rapid, convenient and highly sensitive means to assay cytochrome P-450-mediated metabolism. Like microsomal 7-ethoxycoumarin (7-EC) O-deethylation, EFC

Until recently, all known structures of bacterial cytochromes P450 suggested that substrate access to the buried active site occurred via the F-G region, a surface loop distal to the heme cavity. However, the structure of P450 51 indicates a large
