Hydroxylates (-)-(4S)-limonene to (-)-trans-carveol, a precursor of (-)-carvone, responsible for the typical spearmint flavor note. Fluorinated substrate analogs are hydroxylated with the same regio- and stereochemistry. (4S)-limonene + O2 + reduced [NADPH--hemoprotein reductase] = (1S,5R)-carveol + H(+) + H2O + oxidized [NADPH--hemoprotein reductase] Belongs to the cytochrome P450 family.
