In enzymology a questin monooxygenase (EC 1.14.13.43) is an enzyme that catalyzes the chemical reactionquestin + NADPH + H+ + O2 demethylsulochrin + NADP+ + H2OThe 4 substrates of this enzyme are questin NADPH H+ and O2 whereas its 3 products are demethylsulochrin NADP+ 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.
