Antibodies to mouse liver cytochrome P3-450 (anti-P3-450) and antibodies to rat liver cytochrome P-450d (anti-P-450d-c) inhibit the 0-deethylation of 7-ethoxyresorufin (ER) in liver microsomes of benz(a)pyrene-induced (BP) mice but do not inhibit the 0-deethylase activity in liver microsomes of BP-induced rats. Anti-P3-450 and anti-P-450c inhibit BP-hydroxylation in BP-induced mouse liver microsomes by 20%, but they do not inhibit this reaction at all in BP-induced rat liver microsomes. In a reconstituted monooxygenase system isolated cytochrome P3-450 metabolized 7-ER and BP. In contrast, its homologue, cytochrome P-450d, did not metabolize these substrates. The fraction containing cytochrome P1-450 metabolized 7-ER at a low rate and BP at a rate of 3.6 nmol product/min/nmol cytochrome. Western blot analysis with anti-P-450c + d revealed two bands in SDS-PAGE gels containing BP-induced mouse liver microsomes. The interaction of mouse liver BP-microsomes with anti-P3-450 and anti-P-450d-c was accompanied by the appearance of a single band (cytochrome P3-450).
