Mechanistic studies with N-benzyl-1-aminobenzotriazole-inactivated CYP2B1: differential effects on the metabolism of 7-ethoxy-4-(trifluoromethyl)coumarin, testosterone, and benzphetamine.


Mechanistic studies with N-benzyl-1-aminobenzotriazole (BBT)-inactivated cytochrome P450 2B1 were conducted to determine which step(s) in the reaction cycle had been compromised. Stopped-flow studies, formation of the oxy-ferro intermediate, and analysis of products suggested that the reductive process was slower with the BBT-modified enzyme. The reduced… (More)
