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

recJSingle-stranded-DNA-specific exonuclease RecJ; Function of homologous gene experimentally demonstrated in an other organism; enzyme. (568 aa)    
Predicted Functional Partners:
recQ
ATP-dependent DNA helicase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.

relA
GTP pyrophosphokinase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
  
    0.831
topA
DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]

asnS
Asparaginyl-tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
  
 0.754
gatB
Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase, subunit B; Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl- tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp- tRNA(Asn) or phospho-Glu-tRNA(Gln); Belongs to the GatB/GatE family. GatB subfamily.
     
 0.754
gatA
Glutamyl-tRNA(Gln) amidotransferase, subunit A; Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu- tRNA(Gln).
     
 0.754
cysS
Cysteinyl-tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family.
     
 0.725
asnB
Asparagine synthetase, glutamine-hydrolyzing; Function of strongly homologous gene; enzyme.
      
 0.691
asnB-2
Asparagine synthase (glutamine-hydrolyzing); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
      
 0.691
NIDE2734
Putative Competence protein ComEC/Rec2 related protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
