1 Anti-CYP3A2 antisera inhibited the activities of the S-oxidases catalyzing the reactions from FS to R-FSO (40%) and to S-FSO (60%) at the high substrate concentration and inhibited the activities of the S-oxidases, thus catalyzing reactions from R-FSO and S-FSO to FSO2 (70%) at both high and low substrate concentrations. phenylalanylserine cytochrome P450, family 3, subfamily a, polypeptide 2 Rattus norvegicus
