Ornithine carbamoyltransferase; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline.

Carbamoyl phosphate synthase large subunit; Four CarB-CarA dimers form the carbamoyl phosphate synthetase holoenzyme that catalyzes the production of carbamoyl phosphate; CarB is responsible for the amidotransferase activity; Derived by automated computational analysis using gene prediction method: Protein Homology.

Arginine repressor; Regulates arginine biosynthesis genes.

N-acetyl-gamma-glutamyl-phosphate reductase; Catalyzes the NADPH-dependent reduction of N-acetyl-5- glutamyl phosphate to yield N-acetyl-L-glutamate 5-semialdehyde. Belongs to the NAGSA dehydrogenase family. Type 1 subfamily.

Acetylglutamate kinase; Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate; Belongs to the acetylglutamate kinase family. ArgB subfamily.

Aspartate aminotransferase family protein; Catalyzes the formation of N-acetyl-l-glutamate 5-semialdehyde from 2-oxoglutarate and N(2)-acetyl-L-ornithine; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily.

Bifunctional ornithine acetyltransferase/N-acetylglutamate synthase; Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of N-acetylglutamate from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by transacetylation between N(2)-acetylornithine and glutamate. Belongs to the ArgJ family.

Phosphoribosylglycinamide formyltransferase 2; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.

Asparagine synthetase B; Derived by automated computational analysis using gene prediction method: Protein Homology.
