AAK_NAGK-fArgBP: N-Acetyl-L-glutamate kinase (NAGK) of the fungal arginine-biosynthetic pathway (fArgBP). The nuclear-encoded, mitochondrial polyprotein precursor with an N-terminal NAGK (ArgB) domain (this CD), a central DUF619 domain, and a C-terminal reductase domain (ArgC, N-Acetylglutamate Phosphate Reductase, NAGPR). The precursor is cleaved in the mitochondria into two distinct enzymes (NAGK-DUF619 and NAGPR). Native molecular weights of these proteins indicate that the kinase is an octamer whereas the reductase is a dimer.

The DUF619 domain is described as a putative distant homolog of the acetyltransferase, ArgA, predicted to function in NAG synthase association in fungi. Eukaryotic sequences have an N-terminal mitochondrial transit peptide. Members of this NAG kinase domain CD belong to the Amino Acid Kinase Superfamily (AAK).

N-acetyl-gamma-glutamyl-phosphate phosphate, the product of the second step catalyzed by acetylglutamate kinase, undergoes reductive dephosphorylation to give N-acetylglutamic semialdehyde, which is converted to ornithine by acetylornithine aminotransferase and acetylornithine deacetylase.

In this pathway, glutamate is first N-acetylated and then phosphorylated by NAGK to give phosphoryl NAG, which is converted to NAG-ornithine. There are two variants of this pathway. In one, typified by the pathway in Thermotoga maritima and Pseudomonas aeruginosa, the acetyl group is recycled by reversible transacetylation from acetylornithine to glutamate. The phosphorylation of NAG by NAGK is feedback inhibited by arginine. In photosynthetic organisms, NAGK is the target of the nitrogen-signaling protein PII. Hexameric formation of NAGK domains appears to be essential to both arginine inhibition and NAGK-PII complex formation. NAGK-C are members of the Amino Acid Kinase Superfamily (AAK).

N-acetyl-gamma-glutamyl-phosphate phosphate, the product of the second step catalyzed by acetylglutamate kinase, undergoes reductive dephosphorylation to give N-acetylglutamic semialdehyde, which is converted to ornithine by acetylornithine aminotransferase and acetylornithine deacetylase. AGPR proteins contain an N-terminal Rossmann fold NAD(P)H-binding domain and a C-terminal glyceraldehyde-3-phosphate dehydrogenase (GAPDH)-like catalytic domain and are members of the GAPDH superfamily of proteins. NADP(+) binds in a cleft between these domains and contacts both. There are two related families of N-acetyl-gamma-glutamyl-phosphate reductase, which differ by phylogeny, similarity clustering, and gap architecture in a multiple sequence alignment.

Several bacteria and archaea utilize the amino group-carrier protein, LysW, for lysine biosynthesis from alpha-aminoadipate (AAA). In some cases, such as Sulfolobus, LysW is also used to protect the amino group of glutamate in arginine biosynthesis. After LysW modification, AAA and glutamate are converted to lysine and ornithine, respectively, by a single set of enzymes with dual functions. LysY is the third enzyme in lysine biosynthesis from AAA. LysY shows high sequence identity and functional similarities with ArgC, and they are considered to have evolved from a common ancestor.
