Product autofluorescence activation in the cytochrome P450 monooxygenase system.


The relative increase of the 7-ethoxycoumarin-O-deethylase and the 6,7-dimethoxycoumarin-O-demethylase activities were found 93 and 236% using a reconstituted cytochrome P4502B1:NADPH-P450 reductase system by adding to the reaction mixtures their own products. The assays were irradiated during the reactions with the excitation wavelength maximum of their… (More)
