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.

pupGPurine 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. (274 aa)    
Predicted Functional Partners:
deoD
Purine-nucleoside phosphorylase.
    
 0.967
hprT
Hypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.951
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.929
xpt
Xanthine 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.
  
 
 0.927
ABC3550
Inosine-uridine preferring nucleoside hydrolase.
  
 0.919
ABC3998
Inosine-uridine preferring nucleoside hydrolase.
  
 0.919
cobB
Sir2 family transcriptional regulator; NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form; Belongs to the sirtuin family. Class U subfamily.
    
 0.914
ABC3966
Nicotinate phosphoribosyltransferase; Catalyzes the first step in the biosynthesis of NAD from nicotinic acid, the ATP-dependent synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate. Belongs to the NAPRTase family.
    
 0.914
gde
Guanine deaminase.
    
 0.911
drm
Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family.
