the current study shows that pb induction of monooxygenase activity need not be due entirely to an increase in the amount of cytochrome p-450 or the substrate selectivity of cytochrome p-450 isozyme ( s ) responsible for that activity , but that , in at least one case , the metabolism of bz , pb-induced activity can be due , at least in part , to the induction of a cytochrome p-450 isozyme that relieves substrate inhibition .
