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

lexABifunctional transcriptional repressor of SOS-response/self-cleaving protease LexA; 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. (206 aa)    
Predicted Functional Partners:
recA
Recombinase A RecA; 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.
  
 
 0.997
sulA
UV induced cell division inhibitor SulA; Component of the SOS system and an inhibitor of cell division. Accumulation of SulA causes rapid cessation of cell division and the appearance of long, non-septate filaments. In the presence of GTP, binds a polymerization-competent form of FtsZ in a 1:1 ratio, thus inhibiting FtsZ polymerization and therefore preventing it from participating in the assembly of the Z ring. This mechanism prevents the premature segregation of damaged DNA to daughter cells during cell division.
 
  
 0.951
dinB
DNA polymerase IV DinB; 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.
 
 
 0.900
recN
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA.
   
  
 0.882
argR
Arginine-responsive transcriptional repressor of arginine metabolism ArgR; Regulates arginine biosynthesis genes.
  
   
 0.835
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.
  
   
 0.725
dgkA
Diacylglycerol kinase DgkA; Recycling of diacylglycerol produced during the turnover of membrane phospholipid.
    
 0.718
dnaE
DNA polymerase III alpha subunit DnaE.
 
  
 0.703
dinG
ATP-dependent helicase DinG; DNA-dependent ATPase and 5'-3' DNA helicase.
  
  
 0.703
yebG
UV induced SOS regulon protein YebG.
   
  
 0.703
