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.

RPONPutative sigma factor N RpoN; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (504 aa)    
Predicted Functional Partners:
C3964
Putative nitrogen regulatory IIA protein PtsN; Predicted by orpheus program; predicted by glimmer program.
 
  
 0.916
rpoB
Putative 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
rpoZ
Putative 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.
   
 
 0.911
rpoA
Putative DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.910
rpoC
Putative RNA polymerase, beta prime subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.901
EBIG631
Putative repressor protein luxO; Predicted by orpheus program; predicted by glimmer program.
 
   
 0.898
T3238
Putative sigma-54 modulation protein; Predicted by orpheus program; predicted by glimmer program.
  
  
 0.887
PSPTO195-2
Putative polar flagellar protein FlaK; Predicted by orpheus program; predicted by glimmer program.
 
   
 0.870
PSPTO195
Hypothetical two-component response regulator; Predicted by orpheus program; predicted by glimmer program.
 
   
 0.830
C4817
Putative nitrogen regulation 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.
