CC   -!- FUNCTION: Catalyzes the transfer of the acetyl group from acetyl
CC       coenzyme A to the free amino group of arylamines and hydrazines. Is
CC       able to utilize not only acetyl-CoA, but also n-propionyl-CoA and
CC       acetoacetyl-CoA as acyl donors, although at a lower rate. As acetyl-CoA
CC       and propionyl-CoA are products of cholesterol catabolism and the nat
CC       gene is likely present in the same operon than genes involved in
CC       cholesterol degradation, this enzyme could have a role in the
CC       utilization and regulation of these CoA species.
CC       {ECO:0000250|UniProtKB:P9WJI5}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + an arylamine = an N-acetylarylamine + CoA;
CC         Xref=Rhea:RHEA:16613, ChEBI:CHEBI:13790, ChEBI:CHEBI:50471,
CC         ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.1.5;
CC         Evidence={ECO:0000250|UniProtKB:P9WJI5};
CC   -!- SUBUNIT: Homodimer and homotetramer. {ECO:0000250|UniProtKB:O86309}.
CC   -!- SIMILARITY: Belongs to the arylamine N-acetyltransferase family.
CC       {ECO:0000305}.
