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 ⇌ (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).
