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

Score
gptXanthine-guanine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily. (153 aa)    
Predicted Functional Partners:
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.952
guaC
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides (By similarity).
  
 
 0.930
deoD
Purine nucleoside phosphorylase; COG0813; inosine phosphorylase; PNP.
     
 0.919
ribD
Diaminohydroxyphosphoribosylaminopyrimidine deaminase; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the N-terminal section; belongs to the cytidine and deoxycytidylate deaminase family.
     
 0.682
polA
Putative 5'-3' exonuclease; 5'-3' exonuclease acting preferentially on double-stranded DNA.
     
 0.667
metG
methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
     
 0.663
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
   
 
 0.605
purB
Adenylosuccinate lyase; COG0015; adenylosuccinase; ASL.
  
 
 0.579
grpE1
GrpE protein; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent i [...]
   
   0.551
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; COG0138; bifunctional purine biosynthesis protein PurH; AICAR transformylase; inosinicase; IMP synthetase; ATIC.
  
 
 0.550
