IUBMB Enzyme Nomenclature


Accepted name: aromatic-hydroxylamine O-acetyltransferase

Reaction: N-hydroxy-4-acetylaminobiphenyl + N-hydroxy-4-aminobiphenyl = N-hydroxy-4-aminobiphenyl + N-acetoxy-4-aminobiphenyl

Other name(s): aromatic hydroxylamine acetyltransferase; arylhydroxamate acyltransferase; arylhydroxamate N,O-acetyltransferase; arylhydroxamic acid N,O-acetyltransferase; arylhydroxamic acyltransferase; N,O-acetyltransferase; N-hydroxy-2-acetylaminofluorene N-O acyltransferase

Systematic name: N-hydroxy-4-acetylaminobiphenyl:N-hydroxy-4-aminobiphenyl O-acetyltransferase

Comments: Transfers the N-acetyl group of some aromatic acethydroxamates to the O-position of some aromatic hydroxylamines.
