Cell-free preparations from liver of chick embryo treated with 3-methylcholanthrene catalyzed oxidation of uroporphyrinogen I in the presence of NADPH and 3,4,3',4'-tetrachlorobiphenyl. Extracts of untreated embryo liver or liver from embryo treated with glutethimide, a phenobarbital-like inducer of cytochrome P450 in this system, did not catalyse the oxidation. Direct involvement of cytochrome P450 was demonstrated by inhibition of the oxidation by CO, piperonyl butoxide and specific antisera to the methylcholanthrene-induced cytochrome P450. 2,4,2',4'-tetrachlorobiphenyl was inactive in the oxidation. These results may explain the role of induced cytochrome P450 in experimental uroporphyria. The oxidation may be useful as a simple assay for reactive O2 species.
