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.

Putative 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.

NAD-dependent protein deacetylase, regulatory protein SIR2 family; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the sirtuin family. Class III subfamily.

NAD(+) synthase (glutamine-hydrolyzing) with a nitrilase-like domain; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.

Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).

Nucleoside triphosphate pyrophosphohydrolase MazG; Function of homologous gene experimentally demonstrated in an other organism; enzyme.

Putative nucleotide pyrophosphatase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.

RNA polymerase, beta prime subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

Ketol-acid reductoisomerase; Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate.
