Monocyclic monoterpene ketone monooxygenase
Template:Short description Template:Infobox enzyme Monocyclic monoterpene ketone monooxygenase (Template:EC number, 1-hydroxy-2-oxolimonene 1,2-monooxygenase, dihydrocarvone 1,2-monooxygenase, MMKMO) is an enzyme with systematic name (-)-menthone,NADPH:oxygen oxidoreductase.[1][2][3] This enzyme catalyses the following chemical reaction
- (1) (-)-menthone + NADPH + H+ + O2 (4R,7S)-7-isopropyl-4-methyloxepan-2-one + NADP+ + H2O
- (2) dihydrocarvone + NADPH + H+ + O2 4-isopropenyl-7-methyloxepan-2-one + NADP+ + H2O
- (3) (iso)-dihydrocarvone + NADPH + H+ + O2 6-isopropenyl-3-methyloxepan-2-one + NADP+ + H2O
- (4a) 1-hydroxymenth-8-en-2-one + NADPH + H+ + O2 7-hydroxy-4-isopropenyl-7-methyloxepan-2-one + NADP+ + H2O
- (4b) 7-hydroxy-4-isopropenyl-7-methyloxepan-2-one 3-isopropenyl-6-oxoheptanoate (spontaneous)
Monocyclic monoterpene ketone monooxygenase is a flavoprotein (FAD).
