Cytochrome P450 involved in the biosynthesis of the benzylisoquinoline alkaloid noscapine (PubMed:24324259, PubMed:27378283, PubMed:29610307). Converts (S)-N-methylcanadine to (S)-1-hydroxy-N-methylcanadine (PubMed:24324259, PubMed:27378283). (S)-N-methylcanadine + O2 + reduced [NADPH--hemoprotein reductase] = (S)-1-hydroxy-N-methylcanadine + H(+) + H2O + oxidized [NADPH--hemoprotein reductase] Alkaloid biosynthesis. Highly expressed in capsules (PubMed:22653730). Expressed is stems (PubMed:22653730). Belongs to the cytochrome P450 family.
