N-acetyltransferase 4800495 203600060 2008-04-05T21:20:40Z Arcadian 104523 [[HGSNAT]] '''N-acetyltransferase''' is an [[enzyme]] that [[catalysis|catalyzes]] the transfer of [[acetyl]] groups from [[acetyl-CoA]] to [[arylamine]]s. They have wide specificity for [[aromatic amine]]s, particularly [[serotonin]], and can also catalyze acetyl transfer between arylamines without CoA. EC 2.3.1.5. ==Examples== *[[AANAT]] is the symbol for the enzyme '''arylalkylamine N-acetyltransferase''' and for the gene that encodes it. AANAT is present in animals, bacteria and yeast but in no other living organisms. AANAT belongs to the large superfamily of acetyltransferase enzymes. AANAT is used in organisms to synthesize [[melatonin]] from serotonin. *[[HGSNAT]] {{transferase-stub}} {{chemistry-stub}} [[Category:EC 2.3.1]]
