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

lexATranscriptional repressor, LexA family; 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. (262 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.

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.
  
   
 0.845
clpX
ATP-dependent Clp protease, ATP-binding subunit ClpX; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
  
   
 0.835
argR
Arginine repressor, ArgR; Regulates arginine biosynthesis genes.
  
   
 0.819
ruvA
Holliday junction DNA helicase RuvA; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB.
  
  
 0.810
ftsZ
Cell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.

COGs: COG2176 DNA polymerase III alpha subunit (gram-positive type); InterProIPR012337:IPR000305:IPR006055:IPR006054:IPR 013520; KEGG: bcv:Bcav_1900 DNA polymerase III, epsilon subunit; PFAM: Exonuclease RNase T and DNA polymerase III; Excinuclease ABC C subunit domain protein; PRIAM: DNA-directed DNA polymerase; SMART: Exonuclease; Excinuclease ABC C subunit domain protein; SPTR: D0WQL3 Putative DNA polymerase III, epsilon subunit; TIGRFAM: DNA polymerase III, epsilon subunit; PFAM: Exonuclease; GIY-YIG catalytic domain; TIGRFAM: exonuclease, DNA polymerase III, epsilon subunit family.

uvrA
Excinuclease ABC, A subunit; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by UvrB, the UvrA molecules dissociate.

Arch_0944
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA.
