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. (335 aa)    
Predicted Functional Partners:
fryA
Multiphosphoryl transfer protein 1; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 
 0.805
gltB
Glutamate synthase large subunit; Catalyzes the formation of glutamate from glutamine and alpha-ketoglutarate; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 
 0.731
gltB_1
Glutamate synthase subunit alpha; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 
 0.731
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
    
   0.541
fruB
Bifunctional PTS fructose 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.
   
 
 0.537
guaB_1
IMP dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
    
   0.475
ptsH
PTS sugar transporter; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 
 
 0.469
metG
methionine--tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
    
   0.410
pheT
phenylalanine--tRNA ligase subunit beta; Catalyzes a two-step reaction, first charging a phenylalanine molecule by linking its carboxyl group to the alpha-phosphate of ATP, followed by transfer of the aminoacyl-adenylate to its tRNA; forms a tetramer of alpha(2)beta(2); binds two magnesium ions per tetramer; type 2 subfamily; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
    
   0.410
ribBA
3,4-dihydroxy-2-butanone 4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family.
    
   0.404
