CC -!- FUNCTION: Methyltransferase which catalyzes the transfer of a methyl
CC group onto N-acetylserotonin, producing melatonin (N-acetyl-5-
CC methoxytryptamine). {ECO:0000269|PubMed:24033370}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=N-acetylserotonin + S-adenosyl-L-methionine = H(+) + melatonin
CC + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:15573, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16796, ChEBI:CHEBI:17697, ChEBI:CHEBI:57856,
CC ChEBI:CHEBI:59789; EC=2.1.1.4;
CC Evidence={ECO:0000269|PubMed:24033370};
CC -!- PATHWAY: Aromatic compound metabolism; melatonin biosynthesis;
CC melatonin from serotonin: step 1/2. {ECO:0000305}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P46597}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:24134674}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, leaves, stems and flowers.
CC {ECO:0000269|PubMed:24033370}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. Cation-independent O-methyltransferase family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAT09682.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
