- a steroid + AH2 + O2 a 17alpha-hydroxysteroid + A + H2O
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derive from O miscellaneous. The systematic name of this enzyme class is steroid,hydrogen-donor:oxygen oxidoreductase (17alpha-hydroxylating). Other names in common use include steroid 17alpha-hydroxylase, cytochrome P-45017alpha, cytochrome P-450 (P-45017alpha,lyase), and 17alpha-hydroxylase-C17,20 lyase. This enzyme participates in c21-steroid hormone metabolism. It has 3 cofactors: NADH, NADPH, and Heme.
