Electron transport complex protein, subunit B; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane. Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfB subfamily.

Purine nucleoside phosphorylase 1; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.

Nicotinate dehydrogenase FAD-subunit.

XdhC rossmann domain/XdhC and CoxI family.

Putative glycine dehydrogenase (decarboxylating) subunit 2; 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. C-terminal subunit subfamily.

Uracil phosphoribosyltransferase Upp; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.

Hypoxanthine phosphoribosyltransferase Hpt; Belongs to the purine/pyrimidine phosphoribosyltransferase family.

Xanthine phosphoribosyltransferase Xpt; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.

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