Monocyclic monoterpene ketone monooxygenase (EC 1.14.13.105, 1-hydroxy-2-oxolimonene 1,2-monooxygenase, dihydrocarvone 1,2-monooxygenase, MMKMO) is an enzyme with systematic name (-)-menthone,NADPH:oxygen oxidoreductase. This enzyme catalyses the following chemical reaction
(1) (-)-menthone + NADPH + H+ + O2
⇌
{\displaystyle \rightleftharpoons }
(4R,7S)-7-isopropyl-4-methyloxepan-2-one + NADP+ + H2O
(2) dihydrocarvone + NADPH + H+ + O2
⇌
{\displaystyle \rightleftharpoons }
4-isopropenyl-7-methyloxepan-2-one + NADP+ + H2O
(3) (iso)-dihydrocarvone + NADPH + H+ + O2
⇌
{\displaystyle \rightleftharpoons }
6-isopropenyl-3-methyloxepan-2-one + NADP+ + H2O
(4a) 1-hydroxymenth-8-en-2-one + NADPH + H+ + O2
⇌
{\displaystyle \rightleftharpoons }
7-hydroxy-4-isopropenyl-7-methyloxepan-2-one + NADP+ + H2O
(4b) 7-hydroxy-4-isopropenyl-7-methyloxepan-2-one
⇌
{\displaystyle \rightleftharpoons }
3-isopropenyl-6-oxoheptanoate (spontaneous)
Monocyclic monoterpene ketone monooxygenase is a flavoprotein (FAD).
