Nicotinic acid phosphoribosyltransferase PncB1; Involved in the Preiss-Handler pathway, which is a recycling route that permits the salvage of free nicotinamide (NM) and nicotinic acid (Na) involved in the NAD biosynthesis. Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP. It is not able to use nicotinamide. PncB1 contributes to basal NAD level.

Probable nicotinate-nucleotide pyrophosphatase NadC; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.

Rv1901, (MTCY180.17c), len: 430 aa. Probable cinA-like protein, strong similarity to competence damage proteins CinA of Bacillus subtilis and S. pneumoniae. FASTA results: Q55760 hypothetical 44.7 kDa protein (416 aa) opt: 755, E(): 0, (36.0% identity in 433 aa overlap).

Conserved hypothetical 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. Belongs to the Iojap/RsfS family.

Possible transcriptional regulatory protein NadR (probably AsnC-family); Rv0212c, (MTCY08D5.07c), len: 323 aa. Possible nadR (alternate gene name: nadI), transcriptional regulator,similar to others e.g. NADR_ECOLI|P27278 transcriptional regulator from Escherichia coli (410 aa), FASTA scores: opt: 377, E (): 1e-17, (31.1% identity in 347 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop).

Nicotinic acid phosphoribosyltransferase PncB2; Involved in the Preiss-Handler pathway, which is a recycling route that permits the salvage of free nicotinamide (NM) and nicotinic acid (Na) involved in the NAD biosynthesis. Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP. It is not able to use nicotinamide. PncB2 appears to be responsible for the increased salvage synthesis of NAD during infection of host tissues; Belongs to the NAPRTase family.

Inorganic polyphosphate/ATP-NAD kinase PpnK (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. It can use ATP and other nucleoside triphosphates as well as inorganic polyphosphate (poly(P)) as a source of phosphorus.

Transcriptional regulatory protein; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form (By similarity). Reactivates acetylated acetyl-CoA synthetase (ACS) through an NAD-dependent deacetylation. Is able to ADP-ribosylate itself.

NADH pyrophosphatase; Rv3199c, (MTV014.43)c, len: 313 aa. Probable nudC,NADH pyrophosphatase, similar in particular to Q9CXN4|4933433B15RIK from Mus musculus (Mouse) (356 aa),FASTA scores: opt: 493, E(): 7.4e-24, (39.65% identity in 232 aa overlap); Q9ABG1|CC0266 mutt/NUDIX family protein from Caulobacter crescentus (313 aa), FASTA scores: opt: 479, E(): 5.1e-23, (38.3% identity in 222 aa overlap); O86062|NUDC_PSEAE|NUDC|PA1823 NADH pyrophosphatase from Pseudomonas aeruginosa (278 aa), FASTA scores: opt: 371,2 E(): 3e-16, (43.15% identity in 153 aa overlap); Q9RV62|NUDC_DEIRA|NUDC|DR11 [...]
