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

purRTranscriptional regulator; 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. (341 aa)    
Predicted Functional Partners:
dhaM
Dihydroxyacetone kinase; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 
 0.858
gltB
Catalyzes the formation of glutamate from glutamine and alpha-ketoglutarate; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 
 0.850
nagE
PTS N-acetyl glucosamine transporter subunits IIABC; Phosphoenolpyruvate-dependent sugar phosphotransferase system; catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane; IIB is phosphorylated by IIA and then transfers the phosphoryl group to the sugar; IIC forms the translocation channel; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.628
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.
 
 0.500
fpr_2
Bifunctional PTS system fructose-specific transporter subunit IIA/HPr protein; Phosphoenolpyruvate (PEP)-dependent, sugar transporting phosphotransferase system; catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane; IIA is phosphorylated by phospho-HPr which then transfers the phosphoryl group to the IIB component; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 
 0.473
ppnP
Hypothetical protein; Catalyzes the phosphorolysis of diverse nucleosides, yielding D-ribose 1-phosphate and the respective free bases. Can use uridine, adenosine, guanosine, cytidine, thymidine, inosine and xanthosine as substrates. Also catalyzes the reverse reactions.
      
 0.470
fruA
PTS system fructose-specific transporter subunits IIBC; Phosphoenolpyruvate-dependent sugar phosphotransferase system; catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane; IIB is phosphorylated by IIA and then transfers the phosphoryl group to the sugar; IIC forms the translocation channel; Derived by automated computational analysis using gene prediction method: Protein Homology.
