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

ORA75731.1Transcriptional repressor; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the Fur family. (160 aa)    
Predicted Functional Partners:
ORA69703.1
Glutamate synthase large subunit; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.897
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.
   
   0.799
sigA
RNA polymerase sigma 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 the primary sigma factor during exponential growth.
  
 
 0.713
ORA75640.1
RNA polymerase subunit sigma; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
 
 0.713
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.
   
   0.701
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.
   
   0.696
rpoZ
DNA-directed RNA polymerase subunit omega; 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.
  
   0.686
ORA76679.1
Transcriptional repressor; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the Fur family.
  
     0.619
hypA
Hydrogenase expression protein HupH; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase.
       0.607
katE
Catalase HPII; Serves to protect cells from the toxic effects of hydrogen peroxide.
