FAMILY

Cation-independent O-methyltransferase family

DESCRIPTION

Also known as SOMT1_PAPSO, SOMT1, PSMT1. Methyltransferase involved in the biosynthesis of the benzylisoquinoline alkaloid noscapine (PubMed:22535422, PubMed:22653730, PubMed:29610307). Catalyzes the conversion of (S)-scoulerine to (S)-tetrahydrocolumbamine (PubMed:22535422, PubMed:22653730). Can convert (S)-tetrahydrocolumbamine to tetrahydropalmatine (PubMed:22535422). Can convert (S)-norreticuline to (S)-norcodamine (PubMed:22535422). Can convert (S)-reticuline to (S)-codamine (PubMed:22535422). Substrate preference is (S)-scoulerine > (S)-tetrahydrocolumbamine > (S)-norreticuline > (S)-reticuline (PubMed:22535422). Homodimer.
