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.

purRHTH-type transcriptional repressor PurR (purine nucleotide synthesis repressor); Is the main repressor of the genes involved in the de novo synthesis of purine nucleotides, regulating purB, purC, purEK, purF, purHD, purL, purMN and guaBA expression. PurR is allosterically activated to bind its cognate DNA by binding the purine corepressors, hypoxanthine or guanine, thereby effecting transcription repression. (337 aa)    
Predicted Functional Partners:
gltB
Glutamate synthase, large subunit.
    
 
 0.849
rpoS
RNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
      
 0.621
rpoS-2
RNA polymerase sigma subunit RpoS (sigma-38); 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 master transcriptional regulator of the stationary phase and the general stress response.
      
 0.621
fruB
PTS system, fructose-specific IIA/FPR component.
 
 
 
 0.615
torD
Chaperone protein TorD; Involved in the biogenesis of TorA. Acts on TorA before the insertion of the molybdenum cofactor and, as a result, probably favors a conformation of the apoenzyme that is competent for acquiring the cofactor; Belongs to the TorD/DmsD family. TorD subfamily.
       0.581
tfoX
Putative DNA transformation protein TfoX.
     
 0.571
torR
torCAD operon transcriptional regulatory protein TorR.
 
   
 0.554
rbsK
Ribokinase; Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway.
  
 0.533
ptsH
Phosphocarrier protein Hpr, histidine-containing protein (PTS system).
   
 
 0.525
CED57019.1
PTS system, IIA component.
   
 
 0.523
