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

Score
gptXanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily. (172 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
 0.995
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.978
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.
  
 
 0.948
RPE_0053
PFAM: glutamine amidotransferase class-I; KEGG: rpc:RPC_0056 glutamine amidotransferase class-I.
  
 
 0.947
guaC
IMP dehydrogenase/GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides.
  
 
 0.941
RPE_0354
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.
  
 0.929
RPE_1070
PFAM: metallophosphoesterase; 5'-Nucleotidase domain protein; KEGG: rpc:RPC_1152 5'-nucleotidase-like; Belongs to the 5'-nucleotidase family.
    
 0.927
surE
Exopolyphosphatase / 3'-nucleotidase / 5'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.926
RPE_2885
TIGRFAM: MazG family protein; PFAM: MazG nucleotide pyrophosphohydrolase; phosphoribosyl-ATP pyrophosphohydrolase; KEGG: rpc:RPC_2752 MazG family protein.
    
  0.909
RPE_3215
PFAM: molybdopterin dehydrogenase, FAD-binding; CO dehydrogenase flavoprotein domain protein; KEGG: eba:ebA2062 medium FAD-binding subunit of molybdenum enzyme.
    
 0.907
