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
hptHypoxanthine phosphoribosyl transferase; Function of strongly homologous gene; enzyme; Belongs to the purine/pyrimidine phosphoribosyltransferase family. (189 aa)    
Predicted Functional Partners:
guaA
GMP synthetase (glutamine aminotransferase); Catalyzes the synthesis of GMP from XMP.
  
 
 0.948
guaB
IMP dehydrogeanse; 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
tilS
tRNA(Ile)-lysidine synthase (tRNA(Ile)-lysidine synthetase, tRNA(Ile)-2-lysyl-cytidine synthase); Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. Belongs to the tRNA(Ile)-lysidine synthase family.
 
  
 0.945
gmk
Guanylate kinase (GMP kinase); Essential for recycling GMP and indirectly, cGMP.
  
  
 0.940
purA
Adenylosuccinate synthetase; 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.
  
 
 0.939
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
   
 0.936
xapA
Xanthosine phosphorylase (purine nucleoside phosphorylase); The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
  
 0.936
guaD
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
 
  
 0.934
purH
Bifunctional: IMP cyclohydrolase (N-terminal); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
    
 0.932
ACS41377.1
Putative Glutamine amidotransferase-like protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
 
 0.925
