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. (220 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 (By similarity). Probably involved in base excision repair ; Belongs to the RecA family.
 
 
 0.985
recN
DNA repair protein; May be involved in recombinational repair of damaged DNA. Belongs to the RecN family.

DR_A0345
Hypothetical protein; Identified by Glimmer2; putative.
       0.709
pprA
DNA damage repair protein; dsDNA-binding protein that contributes to the ionizing radiation resistance of D.radiodurans. Plays a role in DNA repair and genome reconstitution, and is necessary for recovery from severe genomic fragmentation as a result of exposure to severe levels of ionizing radiation. In vitro, binds to double-stranded DNA carrying strand breaks and stimulates the DNA end-joining reaction catalyzed by DNA ligases. Thus, PprA plays a critical role in a non-homologous end- joining (NHEJ) pathway for the repair of radiation-induced DNA double- strands breaks. Cannot bind [...]

irrE
Hypothetical protein; Plays a central regulatory role in DNA repair and protection pathways in response to radiation stress. Acts as a site-specific metalloprotease that cleaves and inactivates the repressor protein DdrO, resulting in induced expression of genes required for DNA repair and cell survival after exposure to radiation (By similarity). Regulates the expression of dozens of proteins from different pathways, including the important DNA repair proteins RecA and PprA. Binds to the promoters of recA and pprA.

argR
Arginine repressor/activator; Regulates arginine biosynthesis genes.
  
   
 0.616
recX
Regulatory protein RecX, putative; Modulates RecA activity; Belongs to the RecX family.
  
  
 0.596
cinA
cinA protein; Similar to PID:2251087 percent identity: 100.00; identified by sequence similarity; putative; Belongs to the CinA family.
     
 0.594
recF
recF protein; The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP (By similarity).
  
  
 0.550
DR_0055
Repressor protein, putative; Similar to PID:567887 percent identity: 54.84; identified by sequence similarity; putative.
