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

Score
gptXanthine-guanine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily. (174 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
 0.992
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.969
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.946
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.
  
 
 0.944
RPC_0056
Glutamine amidotransferase class-I.
  
 
 0.935
RPC_1152
5'-Nucleotidase-like; Belongs to the 5'-nucleotidase family.
    
 0.927
RPC_0143
Ham1-like protein.
   
 0.920
RPC_0324
Ham1-like protein; 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.
   
 0.920
surE
3'-nucleotidase / 5'-nucleotidase / exopolyphosphatase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.918
RPC_2752
MazG family protein.
    
  0.905
