IntEnz Enzyme Nomenclature


Accepted name:
glutamate N-acetyltransferase
Other names:
N-acetyl-L-glutamate synthetase
N-acetylglutamate synthase
N-acetylglutamate synthetase
α-N-acetyl-L-ornithine:L-glutamate N-acetyltransferase
acetylglutamate synthetase
acetylglutamate-acetylornithine transacetylase
acetylglutamic synthetase
acetylglutamic-acetylornithine transacetylase
acetylornithine glutamate acetyltransferase
glutamate acetyltransferase
ornithine acetyltransferase
ornithine transacetylase
2-N-acetyl-L-ornithine:L-glutamate N-acetyltransferase
Systematic name:
N2-acetyl-L-ornithine:L-glutamate N-acetyltransferase



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