IUBMB Enzyme Nomenclature


Accepted name: arylamine N-acetyltransferase

Reaction: acetyl-CoA + an arylamine = CoA + an N-acetylarylamine

Other name(s): arylamine acetylase; β-naphthylamine N-acetyltransferase; 4-aminobiphenyl N-acetyltransferase; acetyl CoA-arylamine N-acetyltransferase; 2-naphthylamine N-acetyltransferase; arylamine acetyltransferase; indoleamine N-acetyltransferase; N-acetyltransferase (ambiguous); p-aminosalicylate N-acetyltransferase; serotonin acetyltransferase; serotonin N-acetyltransferase

Systematic name: acetyl-CoA:arylamine N-acetyltransferase

Comments: Wide specificity for aromatic amines, including serotonin; also catalyses acetyl-transfer between arylamines without CoA.
