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

rpoNRNA polymerase sigma-54 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (496 aa)    
Predicted Functional Partners:
ABO_0471
Sigma-54 dependent DNA-binding response regulator.
 
  
 0.956
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.
  
 
 0.919
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.
  
 
 
 0.917
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.
    
 
 0.910
pilS
Two-component sensor histidine kinase; Identified by match to PFAM protein family HMMPF04306 InterPro: Histidine kinase C-terminal; High confidence in function and specificity.
     
 0.904
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.
   
 
 0.878
ABO_0551
Sigma54 modulation protein) identified by sequence similarity;putative InterPro: Sigma 54 modulation protein.
  
  
 0.803
ptsN
Phosphotransferase system, nitrogen regulatory IIA protein; Identified by sequencesimilarity; putative InterPro: phosphoenolpyruvate-dependent sugar phosphotransferase system EIIA 2; Family membership.
 
  
 0.793
ntrC
Two-component response regulator NtrC; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
 
   
 0.788
hydG
Nitrogen regulation protein NR(I; ) identified by match to PFAM protein family HMMPF00072 InterPro: Sigma-54 factor interaction domain; High confidence in function and specificity.
