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.

Score
LHA_1343Putative Hypoxanthine phosphoribosyltransferase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme. (278 aa)    
Predicted Functional Partners:
guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
  
 
 0.943
xapA
Purine nucleoside phosphorylase II; 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.
 
 0.937
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.932
purH
Bifunctional purine biosynthesis protein purH [Includes: Phosphoribosylaminoimidazolecarboxamide formyltransferase; IMP cyclohydrolase].
  
 
 0.929
hpt
Hypoxanthine phosphoribosyltransferase.
  
  
 
0.925
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.
  
 
 0.924
surE
5'-nucleotidase surE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
 0.914
LHA_1905
Homologs of previously reported genes of unknown function; Belongs to the multicopper oxidase YfiH/RL5 family.
  
 
  0.911
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.
    
 0.909
LHA_3095
Inosine 5'-monophosphate dehydrogenase.
    
 0.909
