Cytochrome P450 oxygenase of undefined substrate. Not active with limonene, (+)- or (-)-piperitone, (-)-isopiperitone, piperitenone or (+)-pulegone. The Thr-300 residue involved in activation of molecular oxygen during the hydroxylation reaction is replaced by Ala-300, suggesting that this cytochrome P450 might utilize limonene hydroperoxide as a substrate to produce limonene epoxide. Belongs to the cytochrome P450 family.
