Adenylosuccinate synthetase; 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.

Phosphoribosylaminoimidazolecarboxamide formyltransferase; Involved in de novo purine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.

Non-canonical purine NTP pyrophosphatase; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.

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.

Hypoxanthine-guanine phosphoribosyltransferase; Catalyzes the salvage synthesis of inosine-5'-monophosphate (IMP) and guanosine-5'-monophosphate (GMP) from the purine bases hypoxanthine and guanine, respectively; Derived by automated computational analysis using gene prediction method: Protein Homology.

Glutamate synthase large subunit; Catalyzes the formation of glutamate from glutamine and alpha-ketoglutarate; Derived by automated computational analysis using gene prediction method: Protein Homology.

Amidotransferase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.

PTS fructose transporter subunit IIA; Phosphoenolpyruvate (PEP)-dependent, sugar transporting phosphotransferase system; catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane; the phosphoenolpyruvate-protein phosphotransferase transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein HPr; HPr transfers the phosphoryl group to subunit A; subunit IIA transfers a phosphoryl group to subunit IIB; subunit IIB transfers the phosphoryl group to the substrate; part of the phosphoenolpyruvat [...]
