SYSTEMATIC NAME
IUBMB Comments
steroid,NADPH-hemoprotein reductase:oxygen oxidoreductase (21-hydroxylating)
A P-450 heme-thiolate protein responsible for the conversion of progesterone and 17alpha-hydroxyprogesterone to their respective 21-hydroxylated derivatives, 11-deoxycorticosterone and 11-deoxycortisol. Involved in the biosynthesis of the hormones aldosterone and cortisol. The electron donor is EC 1.6.2.4, NADPH---hemoprotein reductase.
