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

soxSRegulation of superoxide response regulon; Transcriptional activator of the superoxide response regulon of E.coli that includes at least 10 genes such as sodA, nfo, zwf and micF. Binds the DNA sequence 5'-GCACN(7)CAA-3'. It also facilitates the subsequent binding of RNA polymerase to the micF and the nfo promoters (By similarity). (107 aa)    
Predicted Functional Partners:
soxR
Redox-sensing activator of soxS; Activates the transcription of the soxS gene which itself controls the superoxide response regulon. SoxR contains a 2Fe-2S iron- sulfur cluster that may act as a redox sensor system that recognizes superoxide. The variable redox state of the Fe-S cluster is employed in vivo to modulate the transcriptional activity of SoxR in response to specific types of oxidative stress. Upon reduction of 2Fe-2S cluster, SoxR reversibly loses its transcriptional activity, but retains its DNA binding affinity (By similarity).

araC
Transcriptional regulator for ara operon; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose.
  
   
 0.876
acrR
acrAB operon repressor; Residues 1 to 215 of 215 are 99.53 pct identical to residues 1 to 215 of 215 from Escherichia coli K-12 Strain MG1655: B0464.
  
   
 0.814
rpoA
RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
   0.814
marR
Multiple antibiotic resistance protein; Residues 1 to 125 of 125 are 98.40 pct identical to residues 1 to 125 of 125 from Escherichia coli K-12 Strain MG1655: B1530.
   
  
 0.794
tolC
Outer membrane channel; Residues 1 to 495 of 495 are 99.79 pct identical to residues 1 to 495 of 495 from Escherichia coli K-12 Strain MG1655: B3035.
      
 0.792
sodA
Superoxide dismutase, manganese; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems; Belongs to the iron/manganese superoxide dismutase family.
   
  
 0.790
rpoD
RNA polymerase, sigma(70) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
    
 
 0.787
oxyR
Activator, hydrogen peroxide-inducible genes; Hydrogen peroxide sensor. Activates the expression of a regulon of hydrogen peroxide-inducible genes such as katG, gor, ahpC, ahpF, oxyS (a regulatory RNA), dps, fur and grxA. OxyR expression is negatively autoregulated by binding to a 43 bp region upstream of its own coding sequence. OxyR is inactivated by reduction of its essential disulfide bond by the product of GrxA, itself positively regulated by OxyR. Has also a positive regulatory effect on the production of surface proteins that control the colony morphology and auto- aggregation a [...]
