GTP-binding protein; An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism (By similarity). Binds both GDP and GTP. Complements an E.coli era disruption mutant; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. Era GTPase family.

Putative metal-dependent hydrolase; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.

Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family.

Purine nucleoside phosphorylase; 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. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.

Uridine kinase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme.

Purine nucleoside phosphorylase; Cleavage of adenosine and its derivatives; Belongs to the PNP/UDP phosphorylase family.

Thymidine kinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.

Exported 2',3'-cyclic-nucleotide 2'-phosphodiesterase, 2' (or 3') nucleotidase and 5' nucleotidase; Catalyzes the release of inorganic phosphate from 2',3'- cyclic nucleotides through consecutive 2',3'-phosphodiesterase and 3'- (or 2') nucleotidase activities. Also possesses a 5'-nucleotidase activity. Does not catalyze the release of inorganic phosphate from 3',5'-cyclic nucleotides. Probably plays a role in the cellular reprocessing of nucleotides present in the medium, under conditions of phosphate shortage.

Deoxyadenosine/deoxycytidine kinase; Plays an essential role in generating the deoxyribonucleotide precursors dATP AND dCTP for DNA metabolism. The phosphate acceptor specificity is strict toward deoxyadenosine (dAdo) and deoxycytidine (dCyd). The specificity toward the sugar moiety of the nucleoside is less strict. Both 2-deoxyribose, ribose, and arabinose nucleosides are phosphorylated, although the 2-deoxyribonucleosides are preferred. The phosphate donor specificity is dependent on the deoxyribonucleoside substrate, but GTP is efficient with both deoxycytidine and deoxyadenosine. O [...]
