In enzymology, an arylamine N-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + an arylamine CoA + an N-acetylarylamine Thus, the two substrates of this enzyme are acetyl-CoA and arylamine, whereas its two products are CoA and N-acetylarylamine. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:arylamine N-acetyltransferase. Other names in common use include arylamine acetylase, beta-naphthylamine N-acetyltransferase, 4-aminobiphenyl N-acetyltransferase, acetyl CoA-arylamine N-acetyltransferase, 2-naphthylamine N-acetyltransferase, arylamine acetyltransferase, indoleamine N-acetyltransferase, N-acetyltransferase, p-aminosalicylate N-acetyltransferase, serotonin acetyltransferase, and serotonin N-acetyltransferase.
