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

hptPutative hypoxanthine phosphoribosyltransferase; Identified by match to protein family HMM PF00156. (178 aa)    
Predicted Functional Partners:
adk
Adenylate kinase; 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.
 
 
 0.990
EEN83449.1
Purine nucleoside phosphorylase I, inosine and guanosine-specific; 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.
  
 0.948
guaA
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
 
 0.935
EEN83253.1
Inosine 5-monophosphate dehydrogenase; Identified by match to protein family HMM PF00478; match to protein family HMM PF00571.
    
 0.921
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
  
 0.911
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.
  
 
 0.911
purH
Putative phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; Identified by match to protein family HMM PF01808; match to protein family HMM PF02142.
    
 0.904
rdgB
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.
   
 
 0.866
EEN82501.1
Identified by match to protein family HMM PF03819; match to protein family HMM TIGR00444.
    
  0.810
cgtA
Obg family GTPase CgtA; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family.
