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

rpoHRNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (348 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.965
rpoA
DNA-directed RNA polymerase alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.947
rpoZ
DNA-directed RNA polymerase omega subunit; 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.
 
 
 
 0.924
nusA
Transcription elongation protein NusA; Participates in both transcription termination and antitermination.
 
 
 0.920
rpoC
DNA-directed RNA polymerase beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.914
DMR_29460
Hypothetical protein.
 
 
 
 0.912
dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.863
groEL
60 kDa chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
 
 0.862
DMR_20230
GGDEF domain protein.
   
 
 0.849
DMR_27250
Sensor histidine kinase.
  
 
 0.814
