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.

Score
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. (190 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
 0.978
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.955
EDS74818.1
KEGG: lmf:LMOf2365_0150 3.1e-215 inosine-5'-monophosphate dehydrogenase, putative K00088; COG: COG0516 IMP dehydrogenase/GMP reductase; Psort location: Cytoplasmic, score: 8.87.
  
 
 0.951
hpt
KEGG: spn:SP_0012 2.4e-50 hypoxanthine-guanine phosphoribosyltransferase K00760; COG: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; Psort location: Cytoplasmic, score: 9.98; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.942
rdgB
Non-canonical purine NTP pyrophosphatase, RdgB/HAM1 family; 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.
  
 0.922
deoD
KEGG: ssp:SSP0746 6.7e-71 purine nucleoside phosphorylase K03784; COG: COG0813 Purine-nucleoside phosphorylase.
    
 0.911
EDS75509.1
Conserved hypothetical protein, YfiH family; COG: COG1496 Uncharacterized conserved protein; Belongs to the multicopper oxidase YfiH/RL5 family.
    
  0.903
EDS74290.1
Putative permease; COG: COG2233 Xanthine/uracil permeases; Psort location: CytoplasmicMembrane, score: 10.00.
  
 0.826
purA
Adenylosuccinate synthase; 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.
   
 
 0.798
EDS74839.1
Phosphoribosylformylglycinamidine synthase; KEGG: cac:CAC1655 0. purQ, purL; bifunctional enzyme phosphoribosylformylglycinamidine (FGAM) synthase (synthetase domain/glutamine amidotransferase domain) K01952; COG: COG0046 Phosphoribosylformylglycinamidine (FGAM) synthase, synthetase domain; Psort location: Cytoplasmic, score: 8.87.
