IUBMB Enzyme Nomenclature


Accepted name: cysteine-S-conjugate N-acetyltransferase

Reaction: acetyl-CoA + an L-cysteine-S-conjugate = CoA + an N-acetyl L-cysteine-S-conjugate

Glossary: N-acetyl-L-cysteine-S-conjugate = mercapturic acid

Systematic name: acetyl-CoA:S-substituted L-cysteine N-acetyltransferase

Comments: S-Benzyl-L-cysteine and, in decreasing order of activity, S-butyl-L-cysteine, S-propyl-L-cysteine, O-benzyl-L-serine and S-ethyl-L-cysteine, can act as acceptors.
