molecular activities of a reconstituted aryl hydrocarbon hydroxylase ( ec 1.14.14.1 ) containing , respectively , cytochrome p-450i , p-450iia , and p-450iib were 0.224 , 0.250 , and 0.395 ( moles per minute per mole of cytochrome p-450 ) , and were estimated to be one-tenth that of cytochrome p-448 induced in rat liver by 3-methylcholanthrene , indicating the presence of the low inducibility by 3-methylcholanthrene of aryl hydrocarbon hydroxylase in liver microsomes of guinea pigs .
