In enzymology a steroid 17alpha-monooxygenase (EC 1.14.99.9) is an enzyme that catalyzes the chemical reactiona steroid + AH2 + O2 a 17alpha-hydroxysteroid + A + H2OThe 3 substrates of this enzyme are steroid an electron acceptor AH2 and O2 whereas its 3 products are 17alpha-hydroxysteroid the reduction product A and 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.
