Oxidation of carcinogenic benzo[a]pyrene by human and rat cytochrome P450 1A1 and its influencing by cytochrome b5 - a comparative study.
OBJECTIVES: Cytochrome P450 (CYP) 1A1 is the most important enzyme in both activation and detoxification of carcinogenic benzo[a]pyrene (BaP), in combination with microsomal epoxide hydrolase (mEH). To evaluate metabolism of BaP in human, identification of a suitable animal model that mimics the metabolic fate of BaP in human is of grea.....
