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. Ureogenic NAGS is a mitochondrial enzyme catalyzing the formation of NAG from acetylcoenzyme A and L-glutamate. NAGS is an essential allosteric activator of carbamylphosphate synthase I, the first and rate limiting enzyme of the urea cycle. Domain architecture of ureogenic and fungal NAGS consists of an N-terminal NAG kinase-like domain and a C-terminal DUF619 domain. This subgroup also includes the DUF619 domain of the FABP N-acetylglutamate kinase (NAGK), the enzyme that 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. 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). The DUF619 domain function has yet to be characterized. The actual alignment was detected with superfamily member cd04266: Pssm-ID: 417472 Cd Length: 108 Bit Score: 177.26 E-value: 1.29e-52

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.
