Nitrogen 224-232 cytochrome P450 2C3 Oryctolagus cuniculus 26-32 9076658-8 1997 This result indicated that rat CYP2C enzymes have a more rigid regioselectivity than rabbit CYP2C3 for the deamination/N-dealkylation of phenylisopropylamines. Nitrogen 119-120 cytochrome P450 2C3 Oryctolagus cuniculus 92-98
