Molecular function

2-naphthylamine N-acetyltransferase activity, 4-aminobiphenyl N-acetyltransferase activity, acetyl CoA-arylamine N-acetyltransferase activity, acetyl-CoA:arylamine N-acetyltransferase activity, arylamine acetylase activity, arylamine acetyltransferase activity, beta-naphthylamine N-acetyltransferase activity, indoleamine N-acetyltransferase activity, p-aminosalicylate N-acetyltransferase activity

Catalysis of the reaction: acetyl-CoA + an arylamine = CoA + an N-acetylarylamine.
