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

lexALexA 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. (213 aa)    
Predicted Functional Partners:
recA
recA protein; 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.

dinB
DNA-directed DNA polymerase; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII.
 
 
 0.864
hrcA
Heat-inducible transcription repressor HrcA; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
  
   
 0.631
AEG62076.1
Replicative DNA helicase; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. Belongs to the helicase family. DnaB subfamily.
     
 0.588
AEG61273.1
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA.
   
  
 0.580
AEG60257.1
TIGRFAM: PAS sensor protein; PFAM: sigma-54 factor interaction domain-containing protein; PAS fold domain protein; helix-turn-helix Fis-type; KEGG: pth:PTH_1355 transcriptional regulator; SMART: AAA ATPase; PAS domain containing protein.
     
 0.567
dinG
DNA polymerase III, epsilon subunit; 3'-5' exonuclease.
  
  
 0.557
AEG59916.1
TIGRFAM: PAS sensor protein; PFAM: ATP-binding region ATPase domain protein; histidine kinase A domain protein; PAS fold-4 domain protein; PAS fold domain protein; response regulator receiver; Hpt domain protein; KEGG: drm:Dred_2145 multi-sensor hybrid histidine kinase; SMART: ATP-binding region ATPase domain protein; histidine kinase A domain protein; PAS domain containing protein; response regulator receiver.

tig
Trigger factor; Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase; Belongs to the FKBP-type PPIase family. Tig subfamily.
  
   
 0.496
recR
Recombination protein RecR; May play a role in DNA repair. It seems to be involved in an RecBC-independent recombinational process of DNA repair. It may act with RecF and RecO.
