ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.

Putative glutamine-dependent NAD(+) synthetase; Identified by similarity to SP:Q03638; match to protein family HMM PF00733; match to protein family HMM PF02540; match to protein family HMM TIGR00552; Belongs to the NAD synthetase family.

Nicotinate-nucleotide pyrophosphorylase; Identified by similarity to SP:P39666; match to protein family HMM PF01729; match to protein family HMM PF02749; match to protein family HMM TIGR00078; Belongs to the NadC/ModD family.

Stationary-phase survival protein SurE; Identified by similarity to SP:P36664; match to protein family HMM PF01975; match to protein family HMM TIGR00087.

Iojap-related protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.

Riboflavin biosynthesis protein RibD; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.

Pyridoxal phosphate biosynthesis protein PdxJ; Catalyzes the complicated ring closure reaction between the two acyclic compounds 1-deoxy-D-xylulose-5-phosphate (DXP) and 3-amino- 2-oxopropyl phosphate (1-amino-acetone-3-phosphate or AAP) to form pyridoxine 5'-phosphate (PNP) and inorganic phosphate.

YjeF family protein; Bifunctional enzyme that catalyzes the epimerization of the S- and R-forms of NAD(P)HX and the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. This allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. Catalyzes the epimerization of the S- and R-forms of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. This is a prerequisite for the S-specific NAD(P)H-hydrate dehydratase to allow the repair of both epim [...]

GTP-binding protein, GTP1/Obg family; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family.
