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. (192 aa)    
Predicted Functional Partners:
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 0.997
pbuX
Xanthine permease; Identified by similarity to EGAD:30678; match to protein family HMM PF00860; match to protein family HMM TIGR00801.
  
 0.996
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.
  
 
 0.996
hpt
Hypoxanthine phosphoribosyltransferase; Identified by similarity to EGAD:18056; match to protein family HMM PF00156; match to protein family HMM TIGR01203.
  
 0.966
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.962
guaC
Guanosine monophosphate 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; Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
  
 
 0.956
SERP0734
Ham1 family 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
SERP0752
Conserved hypothetical protein TIGR00726; Multicopper oxidase with polyphenol oxidase activity.
 
  
  0.918
deoD
Purine nucleoside phosphorylase; Identified by match to protein family HMM PF01048; match to protein family HMM TIGR00107.
    
 0.909
aroE
Shikimate 5-dehydrogenase; Involved in the biosynthesis of the chorismate, which leads to the biosynthesis of aromatic amino acids. Catalyzes the reversible NADPH linked reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA). It can also use NAD to oxidize shikimate.
