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

punA_3Purine 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. (272 aa)    
Predicted Functional Partners:
deoD
Purine nucleoside phosphorylase; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.990
deoB
Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family.
 
 
 0.987
cdd_1
Cytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis; Belongs to the cytidine and deoxycytidylate deaminase family.
 
 0.980
deoA
Thymidine phosphorylase; Catalyzes the reversible phosphorolysis of thymidine, deoxyuridine and their analogues to their respective bases and 2-deoxyribose 1-phosphate; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.953
hpt
Hypoxanthine phosphoribosyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.939
RihB

 0.935
upp_1
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
  
 
 0.931
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
apt_2
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.927
PncB
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.
