N-hydroxyarylamine O-acetyltransferase  M-CSA #515

The N acetyl-transferase (NAT) family of enzymes N-acetylate arlyhydrazines and arylamines. The transfer of an acetyl group from acetyl coenzyme A to a substrate was first noted in the deactivation of the drug isonizid, where the rate of deactivation varied between individuals, as explained by pharmacogenetic variation in the rate of NAT activity. NAT enzymes are also involved in the metabolism and detoxification of arylamine and arylhydroxylamine carcinogenic substrates.
