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

xptXanthine 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. (192 aa)    
Predicted Functional Partners:
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 0.998
guaB
Protein synonym:IMP dehydrogenase.
  
 
 0.987
OBV_44050
Putative xanthine permease.
  
 0.975
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.961
hpt
Hypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
   
 0.927
rdgB
Nucleoside-triphosphatase; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
  
 0.923
rihB
Pyrimidine-specific ribonucleoside hydrolase RihB.
    
 0.915
OBV_19710
Hypothetical protein.
     
 0.913
OBV_26790
Putative 5'-nucleotidase; Belongs to the 5'-nucleotidase family.
    
 0.911
deoD
Purine nucleoside phosphorylase.
    
 0.910
