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

zurZinc-specific metalloregulatory protein (Fur family); Belongs to the Fur family. (137 aa)    
Predicted Functional Partners:
BMQ_4532
Cation ABC transporter, ATP-binding protein.
  
  
 0.892
BMQ_4531
Cation ABC transporter, permease protein.
  
  
 0.884
rpoA
DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
   0.584
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.
  
 
 0.561
BMQ_2545
CoA binding domain family protein (YneT).
  
    0.538
BMQ_0984
2-cys peroxiredoxin.
  
  
 0.518
BMQ_1334
Putative 2-cys peroxiredoxin.
  
  
 0.518
gltA
Glutamate synthase, large subunit.
     
 0.512
BMQ_4533
Conserved hypothetical protein.
       0.500
birA
Bifunctional protein BirA; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
     
 0.490
