DUF619 domain of N-acetylglutamate Synthase of the fungal arginine-biosynthetic pathway; DUF619-NAGS-FABP: This family includes the DUF619 domain of N-acetylglutamate synthase (NAGS) of the fungal arginine-biosynthetic pathway (FABP). This NAGS (also known as arginine-requiring protein 2 or ARG2) consists of an N-terminal NAG kinase-like domain and a C-terminal DUF619 domain. NAGS catalyzes the formation of NAG from acetylcoenzyme A and L-glutamate. The DUF619 domain, yet to be characterized, is predicted to function in NAGS association in fungi.

NAT, N-acetyltransferase, of N-acetylglutamate synthase; 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 (pfam00696) in some fungal acetylglutamate kinase enzymes. it stabilizes the yeast NAGK, N-acetyl-L-glutamate kinase, slows catalysis and modulates feed-back inhibition by arginine. 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-temrinal domain pfam00696.

DUF619 domain of various N-acetylglutamate Kinases and N-acetylglutamate Synthases; DUF619-like: This family includes the DUF619 domain of various N-acetylglutamate synthases (NAGS) of the urea cycle found in humans and fish, the DUF619 domain of the NAGS of the fungal arginine-biosynthetic pathway (FABP), as well as the DUF619 domain present C-terminal of a NAG kinase-like domain in a limited number of predicted NAGSs found in bacteria and Dictyostelium.

The nuclear-encoded, mitochondrial polyprotein precursor (ARG5,6) consists of an N-terminal NAGK (ArgB) domain, a central DUF619 domain, and a C-terminal reductase domain (ArgC, N-acetylglutamate phosphate reductase).

DUF619 domain of N-acetylglutamate kinase (NAGK) of the fungal arginine-biosynthetic pathway; DUF619-NAGK-FABP: DUF619 domain of N-acetylglutamate kinase (NAGK) of the fungal arginine-biosynthetic pathway (FABP). The nuclear-encoded, mitochondrial polyprotein precursor (ARG5,6) consists of an N-terminal NAGK (ArgB) domain, a central DUF619 domain, and a C-terminal reductase domain (ArgC, N-Acetylglutamate Phosphate Reductase, NAGPR). The precursor is cleaved into two distinct enzymes (NAGK-DUF619 and NAGPR) in the mitochondria. Native molecular weights of these proteins indicate that the kinase is an octamer whereas the reductase is a dimer. Arg5,6 catalyzes the second reaction of arginine biosynthesis; the phosphorylation of the gamma-carboxyl group of NAG to produce N-acetylglutamylphosphate (NAGP) which is subsequently converted to ornithine in two more steps. It also binds and regulates the promoters of nuclear and mitochondrial genes, and may possibly regulate precursor mRNA metabolism. The DUF619 domain function has yet to be characterized.

Domains are color coded according to superfamilies

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
