In enzymology a phylloquinone monooxygenase (23-epoxidizing) (EC 1.14.99.20) is an enzyme that catalyzes the chemical reactionphylloquinone + AH2 + O2 23-epoxyphylloquinone + A + H2OThe 3 substrates of this enzyme are phylloquinone an electron acceptor AH2 and O2 whereas its 3 products are 23-epoxyphylloquinone 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.
