UniProt Comments
Methylates OH residues of flavonoid compounds. Can methylate eriodictyol, luteolin, quercetin and taxifolin (PubMed:16412485). Methylates caffeate to produce ferrulate (PubMed:21210840, Ref. 16). Catalyzes the methylation of monolignols, the lignin precursors. Functions cooperatively with CAD2 in the culm internodes for the biosynthesis of monolignols. May be involved in lignin biosynthesis in leaves and roots (PubMed:21912859). Involved in syringyl lignin biosynthesis. Can function as 5-hydroxyconiferaldehyde O-methyltransferase in the biosynthetic pathway to syringyl lignin (Ref. 16). Involved in melatonin biosynthesis. Can function as acetylserotonin O-methyltransferase. Catalyzes the transfer of a methyl group onto N-acetylserotonin, producing melatonin (N-acetyl-5-methoxytryptamine) (PubMed:26276868).
