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.

recNDNA repair protein; May be involved in recombinational repair of damaged DNA. (579 aa)    
Predicted Functional Partners:
recA
Recombinase A; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.
  
  
 0.833
ppnK
Inorganic polyphosphate/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.
 
   
 0.798
radA
Conserved hypothetical protein; DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function.

uvrB
Excinuclease ABC subunit B; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon binding of the UvrA(2)B(2) complex to a putative damaged site, the DNA wraps around one UvrB monomer. DNA wrap is dependent on ATP binding by UvrB and probably causes local melting of the DNA helix, facilitating insertion of UvrB beta-hairpin between the DNA strands. Then UvrB probes one DNA strand for the presence of a lesion. If a lesion is found the UvrA subunits dissociate [...]

DIP1180
Putative cytotoxin/hemolysin; Similar to Mycobacterium tuberculosis CDC1551 cytotoxin/hemolysin MT1733 SWALL:AAK46002 (EMBL:AE007035) (268 aa) fasta scores: E(): 2.2e-53, 56.56% id in 274 aa, and to Caulobacter crescentus hemolysin A CC1324 SWALL:Q9A8M9 (EMBL:AE005808) (243 aa) fasta scores: E(): 1.2e-29, 42.27% id in 246 aa.

DIP1178
Conserved hypothetical protein; Similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT1731 SWALL:AAK46000 (EMBL:AE007035) (353 aa) fasta scores: E(): 1e-33, 41.06% id in 302 aa, and to Streptomyces coelicolor hypothetical 35.2 kDa protein SCI51.28c SWALL:Q9S212 (EMBL:AL109848) (343 aa) fasta scores: E(): 4e-32, 39.4% id in 302 aa.
     
 0.706
DIP1076
Putative DNA polymerase; Similar to Streptomyces coelicolor putative DNA polymerase SCBAC1A6.08 TR:Q9ADH9 (EMBL:AL589708) (244 aa) fasta scores: E(): 2.6e-12, 42.06% id in 233 aa, and to Rhodobacter capsulatus DNA polymerase III epsilon chain-like protein DnaQ SW:DP3E_RHOCA (O68045) (704 aa) fasta scores: E(): 0.0033, 31.7% id in 164 aa.

polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
  
 0.685
lexA
Transcriptional repressor; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
   
  
 0.673
pheT
Similar to Mycobacterium tuberculosis phenylalanyl-tRNA synthetase beta chain PheT or Rv1650 or MT1688 or MTCY06H11.15 SWALL:SYFB_MYCTU (SWALL:P94985) (831 aa) fasta scores: E(): 4.2e-156, 49.64% id in 844 aa, and to Bacillus subtilis phenylalanyl-tRNA synthetase beta chain PheT SWALL:SYFB_BACSU (SWALL:P17922) (804 aa) fasta scores: E(): 1.8e-53, 30.69% id in 847 aa.
