This is the C-terminal NAT or N-acetyltransferase domain of bifunctional N-acetylglutamate synthase/kinases. It catalyzes the first two steps in arginine biosynthesis. This domain contains the putative NAGS - N-acetylglutamate synthase - active site. It is found at the C-terminus of Neurospora crassa acetylglutamate synthase - amino-acid acetyltransferase, EC: 2.3.1.1. It is also found C-terminal to the amino acid kinase region (Pfam:PF00696) in some fungal acetylglutamate kinase enzymes [1]. it stabilises the yeast NAGK, N-acetyl-L-glutamate kinase, slows catalysis and modulates feed-back inhibition by arginine [2]. This domain is found to be the N-acetyltransferase (NAT) domain, and it has a typical GCN5-related NAT fold and a site that catalyzes NAG synthesis which is located >25 Angstrom away from the L-arginine binding site in the N-terminal domain Pfam:PF00696 [3].
