STRINGSTRING
rpoN protein (Sinorhizobium fredii NGR234) - STRING interaction network
"rpoN" - RNA polymerase sigma-54 factor in Sinorhizobium fredii NGR234
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:
some 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 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. This sigma factor is responsible for the expression of the nitrogen fixation genes (nif operon), glnA and dctA for dicarboxylate transport. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator proteins NifA, NtrC, or DctD for the expression of the regulated proteins (519 aa)    
Predicted Functional Partners:
nifA
Nif-specific regulatory protein; Required for activation of most nif operons, which are directly involved in nitrogen fixation (594 aa)
   
     
  0.927
ntrC
Sensor glnL; nitrogen regulator I, NRI (484 aa)
 
     
  0.887
rpoH
annotation not available (301 aa)
           
  0.830
NGR_c00150
annotation not available (154 aa)
   
  0.797
NGR_c28410
annotation not available (514 aa)
 
     
  0.784
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (336 aa)
       
 
  0.779
rpoC
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1401 aa)
   
 
 
  0.758
ntrX
annotation not available (454 aa)
 
     
  0.747
hpf
Ribosome hibernation promoting factor; Required for dimerization of active 70S ribosomes into 100S ribosomes in stationary phase; 100S ribosomes are translationally inactive and sometimes present during exponential growth (190 aa)
   
   
  0.721
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (1380 aa)
