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

BF49_0118RNA polymerase sigma54 factor RpoN; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (537 aa)    
Predicted Functional Partners:
ntrC
Nitrogen regulation protein 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.

Formate hydrogenlyase transcriptional activator.
 
  
 0.833
BF49_0116
PTS IIAlike nitrogenregulatory protein PtsN.
 
  
 0.826
rpoC
DNAdirected RNA polymerase beta subunit EC 2776; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 
 0.807
BF49_2829
Transcriptional activator of acetoin dehydrogenase operon AcoR.
 
  
 0.803
BF49_5893
DNAdirected RNA polymerase alpha subunit EC 2776.
 
 
 0.797
BF49_5901
DNAdirected RNA polymerase alpha subunit EC 2776.
 
 
 0.797
BF49_4501
Transcriptional regulatory protein flbD.
 
   
 0.794
rpoZ
DNAdirected RNA polymerase omega subunit EC 2776; 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.
   
 
 0.793
BF49_0517
Trehalose6phosphate phosphatase EC 31312; Removes the phosphate from trehalose 6-phosphate to produce free trehalose.
