This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is N2-acetyl-L-ornithine:L-glutamate N-acetyltransferase. Other names in common use include ornithine transacetylase, alpha-N-acetyl-L-ornithine:L-glutamate N-acetyltransferase, acetylglutamate synthetase, acetylglutamate-acetylornithine transacetylase, acetylglutamic synthetase, acetylglutamic-acetylornithine transacetylase, acetylornithinase, acetylornithine glutamate acetyltransferase, glutamate acetyltransferase, N-acetyl-L-glutamate synthetase, N-acetylglutamate synthase, N-acetylglutamate synthetase, ornithine acetyltransferase, and 2-N-acetyl-L-ornithine:L-glutamate N-acetyltransferase. This enzyme participates in urea cycle and metabolism of amino groups.
