Steroid 17alpha-monooxygenase (EC 1.14.99.9 steroid 17alpha-hydroxylase cytochrome P-45017alpha cytochrome P-450 (P-45017alphalyase) 17alpha-hydroxylase-C1720 lyase) is an enzyme with system name steroidhydrogen-donor:oxygen oxidoreductase (17alpha-hydroxylating). This enzyme catalyses the following chemical reaction a steroid + AH2 + O2 a 17alpha-hydroxysteroid + A + H2OSteroid 17a-monooxygenase requires NAD(P)H and P-450.
