IUBMB Enzyme Nomenclature


Accepted name: glutamate N-acetyltransferase

Reaction: N2-acetyl-L-ornithine + L-glutamate = L-ornithine + N-acetyl-L-glutamate

Other name(s): ornithine transacetylase; α-N-acetyl-L-ornithine:L-glutamate N-acetyltransferase; acetylglutamate synthetase; acetylglutamate-acetylornithine transacetylase; acetylglutamic synthetase; acetylglutamic-acetylornithine transacetylase; acetylornithine glutamate acetyltransferase; glutamate acetyltransferase; N-acetyl-L-glutamate synthetase; N-acetylglutamate synthase; N-acetylglutamate synthetase; ornithine acetyltransferase; 2-N-acetyl-L-ornithine:L-glutamate N-acetyltransferase; acetylornithinase (ambiguous)

Systematic name: N2-acetyl-L-ornithine:L-glutamate N-acetyltransferase

Comments: Also has some hydrolytic activity on acetyl-L-ornithine, but the rate is 1% of that of transferase activity.
