N-acetyl-L-aspartate:L-glutamate ligase (ADP, N-acetyl-L-aspartyl-L-glutamate-forming)
The enzyme, found in animals, produces the neurotransmitter N-acetyl-L-aspartyl-L-glutamate. One isoform also has the activity of EC 6.3.1.17, beta-citrylglutamate synthase [2], while another isoform has the activity of EC 6.3.2.42, N-acetylaspartylglutamylglutamate synthase [3].
