Acetyltransferase involved in the biosynthesis of the benzylisoquinoline alkaloid noscapine (PubMed:25485687, PubMed:27378283, PubMed:29610307). Converts (13S,14R)-1,13-dihydroxy-N-methylcanadine to (13S,14R)-13-O-acetyl-1-hydroxy-N-methylcanadine (PubMed:25485687, PubMed:27378283). (13S,14R)-1,13-dihydroxy-N-methylcanadine + acetyl-CoA = (13S,14R)-13-O-acetyl-1-hydroxy-N-methylcanadine + CoA Alkaloid biosynthesis. Belongs to the plant acyltransferase family.
