STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nadCProbable nicotinate-nucleotide pyrophosphatase NadC; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family. (285 aa)    
Predicted Functional Partners:
nadA
Probable quinolinate synthetase NadA; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate; Belongs to the quinolinate synthase A family. Type 2 subfamily.
 
 
 0.999
nadB
Probable L-aspartate oxidase NadB; Catalyzes the oxidation of L-aspartate to iminoaspartate.
  
 0.999
pncB1
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.
   
 0.993
nadR
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).
  
 
 0.981
nadD
Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
  
 
 0.979
cinA
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).
  
 
 0.971
pncB2
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.
