Probable inorganic polyphosphate/ATP-NAD kinase (Poly(P)/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.

NH(3)-dependent NAD+ synthetase NadE; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.

Quinolinate phosphoribosyl transferase; Belongs to the NadC/ModD family.

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.

Alanine dehydrogenase/PNT; C-terminal.

NAD(P) transhydrogenase subunit alpha part 2.

NAD(p) transhydrogenase subunit beta; The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane; Belongs to the PNT beta subunit family.

Gamma-glutamyl phosphate reductase; Catalyzes the NADPH-dependent reduction of L-glutamate 5- phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. Belongs to the gamma-glutamyl phosphate reductase family.

GTP-binding protein; 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.
