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.

rpoHRNA polymerase sigma-32 factor (rpoH); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes. (281 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase, beta chain (rpoB); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.949
rpoA
DNA-directed RNA polymerase, alpha chain (rpoA); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.934
dnaJ
Heat shock protein (dnaJ); Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ [...]
   
 
 0.911
rpoZ
DNA-directed RNA polymerase, omega chain (rpoZ); Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits (By similarity).
  
 
 
 0.909
rpoC
DNA-directed RNA polymerase, beta' chain (rpoC); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.891
groL
Heat shock protein (groEL); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
   
 
 0.804
rpoD
RNA polymerase sigma-70 factor (rpoD); 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.
  
  
0.767
dnaK
Heat shock protein 70 (dnaK); Acts as a chaperone; Belongs to the heat shock protein 70 family.
   
 
 0.744
nusA
N utilization substance protein A (nusA); Participates in both transcription termination and antitermination.
  
 
 0.723
dksA
dnaK suppressor protein (dksA); Transcription factor that acts by binding directly to the RNA polymerase (RNAP). Required for negative regulation of rRNA expression and positive regulation of several amino acid biosynthesis promoters. Also required for regulation of fis expression.
