Arylamine N-acetyltransferase

281 amino acids

Catalyzes the acetyl-CoA-dependent N-acetylation of aromatic amines, and, probably, the O-acetylation of N-hydroxyarylamines. In vitro, catalyzes the N-acetylation of various arylamines such as aminobenzoic acid, aminophenol, aminotoluene, phenetidine, anisidine, aniline, isoniazid and 2-amino-fluorene (PubMed:10806332, PubMed:23452042). N-hydroxyarylamine O-acetyltransferase activity has not been assayed directly, however, NhoA activity is required for the mutagenicity of nitroaromatic compounds, suggesting that it also has O-acetyltransferase activity (Probable).

Belongs to the arylamine N-acetyltransferase family.

Arylamine N-acetyltransferase / N-hydroxyarylamine O-acetyltransferase

281 amino acids

Catalyzes both the acetyl-CoA-dependent N-acetylation of aromatic amines and the O-acetylation of N-hydroxyarylamines. In vitro, catalyzes the O-acetylation of N-hydroxy-Glu-P-1, and the N-acetylation of isoniazid and 2-aminofluorene.

Belongs to the arylamine N-acetyltransferase family.
