In enzymology an androst-4-ene-317-dione monooxygenase (EC 1.14.99.12) is an enzyme that catalyzes the chemical reactionandrost-4-ene-317-dione + AH2 + O2 3-oxo-1317-secoandrost-4-ene-1713alpha-lactone + A + H2OThe 3 substrates of this enzyme are androst-4-ene-317-dione an electron acceptor AH2 and O2 whereas its 3 products are 3-oxo-1317-secoandrost-4-ene-1713alpha-lactone 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.
