Glossary: limonene = a monoterpenoid
(S)-limonene = (–)-limonene

Other name(s): (–)-limonene 6-hydroxylase; (–)-limonene 6-monooxygenase; (–)-limonene,NADPH:oxygen oxidoreductase (6-hydroxylating)

Systematic name: (S)-limonene,[reduced NADPH —hemoprotein reductase]:oxygen oxidoreductase (6-hydroxylating)

Comments: A cytochrome P-450 (heme thiolate) enzyme. The enzyme participates in the biosynthesis of (–)-carvone, which is responsible for the aroma of spearmint.
