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

cinARv1901, (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). (430 aa)    
Predicted Functional Partners:
nadD
Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
  
 
 0.978
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.
  
 
 0.977
nadC
Probable nicotinate-nucleotide pyrophosphatase NadC; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
  
 
 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.

nudC
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 [...]

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).
    
 0.948
nadE
Glutamine-dependent NAD(+) synthetase NadE (NAD(+) synthase [glutamine-hydrolysing]); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source. In vitro, can also use ammonia with comparable specific activity.
  
  
 0.905
pgsA3
Probable phosphatidylglycerophosphate synthase; Probably catalyzes the synthesis of phosphatidylglycerophosphate by transferring a phosphatidyl group from CDP-diacylglycerol to glycerol 3-phosphate. Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
  
 0.880
pgsA2
Putative cardiolipin synthase; May catalyze the biosynthesis of cardiolipin from phosphatidylglycerol (PG) and CDP-diacylglycerol. Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
  
  
 0.823
pgsA1
Phosphatidylinositol phosphate synthase; Catalyzes the conjugation of the 1'-hydroxyl group of D-myo- inositol-3-phosphate (also named L-myo-inositol-1-phosphate) with a lipid tail of cytidine diphosphate diacylglycerol (CDP-DAG), forming phosphatidylinositol phosphate (PIP) and CMP. PIP is a precursor of phosphatidylinositol (PI) which is an essential lipid for mycobacteria required for formation of their cell wall.
