Protein
Serotonin N-acetyltransferase 2, chloroplastic
Organism
Oryza sativa subsp. japonica
Function
Catalyzes the N-acetylation of serotonin into N-acetylserotonin, the penultimate step in the synthesis of melatonin (PubMed:27121038). Catalyzes in vitro the N-acetylation of tryptamine to produce N-acetyltryptamine, 5-methoxytryptamine to produce melatonin and tyramine to produce N-acetyltyramine (PubMed:27121038).
