Name
monoprenyl isoflavone epoxidase;
monoprenyl isoflavone monooxygenase;
7-O-methylluteone:O2 oxidoreductase;
7-O-methylluteone,NADPH:O2 oxidoreductase
Class

Acting on paired donors, with incorporation or reduction of molecular oxygen;
Miscellaneous
Sysname
7-O-methylluteone,NADPH:oxygen oxidoreductase
Reaction(IUBMB)
7-O-methylluteone + NADPH + H+ + O2 = dihydrofurano derivatives + NADP+ + H2O [RN:R05741]
Reaction(KEGG)
R05741
Substrate
7-O-methylluteone [CPD:C07290];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
dihydrofurano derivative [CPD:C07291];
NADP+ [CPD:C00006];
H2O [CPD:C00001]
Comment
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 non-enzymically converted into the corresponding dihydrofurano derivative. The enzyme in the fungus Botrytis cinerea is induced by the substrate analogue, 6-prenylnaringenin.
