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

hptHypoxanthine-guanine phosphoribosyltransferase. (189 aa)    
Predicted Functional Partners:
KRG22823.1
S-methyl-5'-thioinosine phosphorylase.
  
 0.903
guaA_2
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
  
 
 0.857
guaB
Inosine-5'-monophosphate 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.
    
 0.856
nrdA
Ribonucleoside-diphosphate reductase 1 subunit alpha; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
  
 
 0.834
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
  
 0.816
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.
  
 
 0.812
purH
Bifunctional purine biosynthesis protein PurH.
    
 0.798
KRG20839.1
S-methyl-5'-thioinosine phosphorylase; Purine nucleoside phosphorylase involved in purine salvage.
  
 0.767
purB
Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
    
 0.750
guaA_1
GMP synthase [glutamine-hydrolyzing].
    
 0.744
