IUBMB Enzyme Nomenclature


Accepted name: N-hydroxyarylamine O-acetyltransferase

Reaction: acetyl-CoA + an N-hydroxyarylamine = CoA + an N-acetoxyarylamine

Other name(s): arylhydroxamate N,O-acetyltransferase; arylamine N-acetyltransferase; N-hydroxy-2-aminofluorene-O-acetyltransferase

Systematic name: acetyl-CoA:N-hydroxyarylamine O-acetyltransferase

Comments: The enzyme from liver, but not that from bacteria, can also catalyse N-acetylation of arylamines and N,O-acetylation of arylhydroxamates.
