(S)-limonene 7-monooxygenase (EC 1.14.14.52) is an enzyme that catalyzes the chemical reaction
-Limonen.svg)
-Perillyl_alcohol.svg)
The four substrates of this enzyme are (−)-(S)-limonene, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen, and a proton. Its products are (−)-perillyl alcohol, 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 (7-hydroxylating). Other names in common use include (−)-limonene 7-monooxygenase, (−)-limonene hydroxylase, (−)-limonene monooxygenase, and (−)-limonene,NADPH:oxygen oxidoreductase (7-hydroxylating).[1] In Perilla frutescens it is part of the biosynthetic pathway to perillaldehyde.[2]
