Benzo(a)pyrene 92-106 cytochrome P450 2B4 Oryctolagus cuniculus 74-82 6270135-3 1981 In contrast, an inhibitory effect of flavone on benzo[a]pyrene metabolism was observed when cytochrome P-450LM2, cytochrome P-450LM3b, or cytochrome P-450LM6 was used in the reconstituted system. Benzo(a)pyrene 48-62 cytochrome P450 2B4 Oryctolagus cuniculus 92-111 6270135-5 1981 Smaller effects of 7,8-benzoflavone were observed on the metabolism of benzo[a]pyrene by the cytochrome P-450LM2-, cytochrome P-450LM3b-, and cytochrome P-450LM4-dependent monooxygenase systems. Benzo(a)pyrene 71-85 cytochrome P450 2B4 Oryctolagus cuniculus 93-112 277915-3 1978 P-450(LM2) is more active than P-450(LM4) in the metabolism of BzP and in its conversion to products that bind to DNA. Benzo(a)pyrene 63-66 cytochrome P450 2B4 Oryctolagus cuniculus 0-9 7336952-1 1981 The specificity of electrophoretically homogeneous preparations of rabbit liver microsomal cytochrome P-450LM2-4 towards oxygenation of n-hexane, 7-ethoxyresorufin and benzo(a)pyrene was examined using a reconstituted system consisting of cytochrome P-450, NADPH-cytochrome P-450 reductase and dilauroylphosphatidylcholine. Benzo(a)pyrene 168-182 cytochrome P450 2B4 Oryctolagus cuniculus 91-110 277915-5 1978 The ratio of activity (percent substrate metabolized) with BzP relative to that with (-)trans-7,8-diol is 21 for P-450(LM2) and 0.3 for P-450(LM4); P-450(LM1), P-450(LM3b), and P-450(LM7) gave intermediate ratios. Benzo(a)pyrene 59-62 cytochrome P450 2B4 Oryctolagus cuniculus 113-122
