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

PP_0747Hypoxanthine-guanine phosphoribosyltransferase. (185 aa)    
Predicted Functional Partners:
xpt
Xanthine phosphoribosyltransferase; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.
   
 0.987
gmk
Deoxyguanylate kinase / guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
  
 0.987
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
   
 0.980
guaB
IMP dehydrogenase and single strand DNA binding factor; 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.
  
 
 0.976
guaA
Glutamine-hydrolyzing GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 
 0.952
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Purines,pyrimidines,nucleosides,andnucleotides : Purine ribonucleotide biosynthesis.
    
 0.949
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.
  
 
 0.948
PP_0591
Adenine deaminase; Catalyzes the hydrolytic deamination of adenine to hypoxanthine. Plays an important role in the purine salvage pathway and in nitrogen catabolism.
   
 
 0.932
guaD
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
 
  
 0.927
Nuh
Ribonucleoside hydrolase; Function experimentally demonstrated in the studied strain; enzyme; Purines,pyrimidines,nucleosides,andnucleotides : Nucleotide and nucleoside interconversions; Belongs to the IUNH family.
     
 0.920
