(S)-limonene 6-monooxygenase (EC 1.14.14.51) is an enzyme that catalyzes the chemical reaction
-Limonen.svg.png)
The four substrates of this enzyme are (−)-(S)-limonene, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen and a proton. Its products are (−)-trans-carveol, oxidised NADP+, and water.[1][2]
This enzyme is a cytochrome P450 protein containing heme. This oxidoreductase, which uses molecular oxygen as oxidant is in a group with systematic name (S)-limonene,NADPH:oxygen oxidoreductase (6-hydroxylating). Other names in common use include (−)-limonene 6-hydroxylase, (−)-limonene 6-monooxygenase, and (−)-limonene,NADPH:oxygen oxidoreductase (6-hydroxylating).[1] It is part of the biosynthetic pathway that leads to (−)-carvone, a compound giving spearmint its aroma.[2]
