NAD(P)H-flavin reductase; catalyzes the reversible oxidation/reduction of NAD(P) and flavine mononucleotide; in Salmonella and E. coli this protein also reduces aquacob(III)alamin to cob(II)alamin; Derived by automated computational analysis using gene prediction method: Protein Homology.

Dihydroorotase; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate.

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.

Carbamoyl-phosphate synthase small subunit; Catalyzes production of carbamoyl phosphate from bicarbonate and glutamine in pyrimidine and arginine biosynthesis pathways; forms an octamer composed of four CarAB dimers; Derived by automated computational analysis using gene prediction method: Protein Homology.

Aspartate carbamoyltransferase; Catalyzes the conversion of carbamoyl phosphate and l-aspartate to yield orthophosphate and n-carbamoyl-l-aspartate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the aspartate/ornithine carbamoyltransferase superfamily.

Cyanophycinase; Catalyzes the hydrolytic cleavage of a subset of L- isoaspartyl (L-beta-aspartyl) dipeptides. Used to degrade proteins damaged by L-isoaspartyl residues formation. Belongs to the peptidase M38 family.

Orotidine 5'-phosphate decarboxylase; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP); Belongs to the OMP decarboxylase family. Type 1 subfamily.

phenylalanine--tRNA ligase subunit beta; Catalyzes a two-step reaction, first charging a phenylalanine molecule by linking its carboxyl group to the alpha-phosphate of ATP, followed by transfer of the aminoacyl-adenylate to its tRNA; forms a tetramer of alpha(2)beta(2); binds two magnesium ions per tetramer; type 2 subfamily; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.

IMP dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
