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
HptHypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family. (181 aa)    
Predicted Functional Partners:
guaA
Hypothetical GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 
 0.992
guaB
Hypothetical protein; 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.
    
 0.971
MesJ
Predicted ATPase; 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.
 
  
 0.948
Gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
  
 0.939
PurA
Adenylosuccinate synthase; 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.
  
 
 0.938
Apt
Adenine/guanine phosphoribosyltransferases and related PRPP-binding proteins; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
   
 0.936
PurH
AICAR transformylase/IMP cyclohydrolase PurH; Only IMP cyclohydrolase domain in Aful.
    
 0.931
Adk
Adenylate kinase and related kinases; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism; Belongs to the adenylate kinase family.
 
  
 0.930
PTH_0801
Hypothetical protein; Containing FOG:CBS domain (COG0517) and GGDEF domain.
    
 0.912
SsnA-2
Cytosine deaminase and related metal-dependent hydrolases; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
    
 0.911
