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.
Structural studies
As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes 1GX3, 1W5R, 1W6F, 2BSZ, 2IJA, 2PFR, and 2PQT.
