An improved in vitro fluorometric assay of the O-deethylation of 7-ethoxycoumarin which is at least 10 times more sensitive than existing methods is described. Nearly quantitative recovery of the product which is essentially free of fluorescent impurities is obtained by

Cytochrome P450 purified from phenobarbital-induced rat liver microsomes was acetylated at 3 lysyl residues. When reconstituted with purified NADPH-cytochrome P450 reductase, the modified cytochrome showed full activity and substrate-induced spectral changes with d-benzphetamine. With 7-ethoxycoumarin, neither enzymic activity nor binding

Azole fungicides, designed to halt fungal growth by specific inhibition of fungal cytochrome P450 (CYP51), inhibit cytochrome P450s involved in the metabolism of xenobiotics in several non-target organisms thus raising environmental concern. The present study investigates the degree by which
