EC 1.14 - Acting on paired donors, with incorporation or reduction of molecular oxygen. The oxygen incorporated need not be derived from O2
EC 18.104.22.168 - Monoprenyl isoflavone epoxidase
IntEnz Enzyme Nomenclature
monoprenyl isoflavone monooxygenase
- 7-O-methylluteone + NADPH + H+ + O2 = dihydrofurano derivatives + NADP+ + H2O
A flavoprotein (FAD) with high specificity for monoprenyl isoflavone. The product of the prenyl epoxidation reaction contains an oxygen atom derived from O2, but not from H2O. It is slowly and nonenzymically converted into the corresponding dihydrofurano derivative. The enzyme in the fungus Botrytis cinerea is induced by the substrate analogue, 6-prenylnaringenin.
