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

fnrTranscriptional regulator (FNR/CAP family); It is involved in the activation of genes necessary for anaerobic respiration. (238 aa)    
Predicted Functional Partners:
glnK
Nitrogen-regulated PII-like regulator protein; Required for full induction of the nrgAB operon under conditions of ammonium limitation.
      
 0.906
narG
Nitrate reductase (alpha subunit); The alpha chain is the actual site of nitrate reduction.
  
  
 0.891
arfM
Transcriptional regulator; Activates, in anaerobic conditions, the transcription of the fermentative operons lctEP and alsDS, of the hmp gene encoding a flavohemoglobin-like protein, the nitrite reductase operon nasDE and the heme biosynthesis genes hemN and hemZ.
   
  
 0.808
nasD
Assimilatory nitrite reductase subunit; Required for nitrite assimilation.
  
  
 0.796
narK
Nitrite extrusion permease; Involved in excretion of nitrite produced by the dissimilatory reduction of nitrate; Belongs to the major facilitator superfamily. Nitrate/nitrite porter (TC 2.A.1.8) family.
  
  
 0.793
rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.767
rpoC
RNA polymerase (beta' subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.741
amtB
Ammonium transporter; Functions as an ammonium and methylammonium transporter in the absence of glutamine. Required for ammonium utilization at low concentrations or at low pH values, when ammonium is the single nitrogen source. Required for binding of NrgB to the membrane. Interaction between GlnK-AmtB complex and TnrA protects TnrA from proteolytic degradation.
      
 0.733
rpoA
RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
   0.723
nasE
Assimilatory nitrite reductase subunit; Required for nitrite assimilation. Required for activity of the reductase (By similarity).
   
  
 0.721
