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. (202 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
 0.975
guaA-2
GMP synthase (glutamine-hydrolyzing) domain protein; KEGG: bth:BT2419 2.8e-184 putative GMP synthase [glutamine-hydrolyzing] K01951; COG: COG0518 GMP synthase - Glutamine amidotransferase domain; Psort location: Cytoplasmic, score: 8.87.
  
 0.975
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.956
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.

hpt
KEGG: tte:TTE2394 2.0e-53 hpt; hypoxanthine-guanine phosphoribosyltransferase K00760; COG: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; Psort location: Cytoplasmic, score: 9.98; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.940
gmk_1
Hypothetical protein; KEGG: tws:TW406 1.8e-09 gmk; guanylate kinase K00942; COG: COG0194 Guanylate kinase; Psort location: Cytoplasmic, score: 8.87.
  
 
 0.940
GuaB_1
KEGG: lin:lin0179 3.1e-217 similar to inosine monophosphate dehydrogenase K00088; COG: COG0516 IMP dehydrogenase/GMP reductase; Psort location: Cytoplasmic, score: 8.87.
  
 
 0.933
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.
  
 0.924
guaD
Putative guanine deaminase; KEGG: cac:CAC0282 1.1e-104 cytosine/guanine deaminase related protein K01487; COG: COG0402 Cytosine deaminase and related metal-dependent hydrolases; Psort location: Cytoplasmic, score: 8.87.
  
  
 0.918
surE
KEGG: mth:MTH1435 4.0e-34 surE; acid phosphatase K03787; COG: COG0496 Predicted acid phosphatase; Psort location: Cytoplasmic, score: 8.87.
