Here, we present the X-ray crystal structure of human N-acetyl serotonin methyltransferase (ASMT), the last enzyme of the melatonin biosynthesis pathway. Melatonin synthesis requires serotonin, which is first acetylated by the arylalkylamine N-acetyltransferase (AA-NAT) to produce N-acetyl serotonin (NAS) (Fig. 1A). Then, acetyl serotonin methyltransferase (ASMT, also known as hydroxyindole O-methyltransferase or HIOMT) produces melatonin by transferring a methyl group from the cofactor S-adenosyl-L-methionine (SAM) to NAS. |
