GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP

Glycine dehydrogenase (decarboxylating); The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family

Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF- independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism

3,4-dihydroxy-2-butanone 4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family

Inosine-5'-monophosphate 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

Bifunctional purine biosynthesis protein PurH; Involved in de novo purine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology

Phosphoribosylamine--glycine ligase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the GARS family

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

Aminomethyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the GcvT family
