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.

rpoNRNA polymerase factor sigma-54; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (535 aa)    
Predicted Functional Partners:
nifA
Transcriptional regulator NifA; Identified by sequence similarity; putative.
 
   
 0.921
rpoC
DNA-directed RNA polymerase beta' chain; Identified by sequence similarity; putative.
 
 
 0.908
ntrC
Nitrogen assimilation regulatory protein; 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.
 
  
 0.875
ENN84664.1
Two-component sensor histidine kinase protein; Identified by sequence similarity; putative.
 
 
 0.862
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.
 
 
 0.860
tacA
Sigma-54-dependent transcriptional regulator (activator) protein; Identified by sequence similarity; putative.
 
  
 0.839
rpoZ
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.
   
 
 0.826
rpoB
DNA-directed RNA polymerase protein, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.823
dctD
C4-dicarboxylate transport transcriptional regulatory protein dctD; Identified by sequence similarity; putative.
 
  
 0.814
ntrX
Nitrogen assimilation regulatory protein ntrX; Identified by sequence similarity; putative.
 
  
 0.797
