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

punAPutative purine 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. (269 aa)    
Predicted Functional Partners:
deoD
Putative purine nucleoside phosphorylase.
    
 0.958
deoB
Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family.
  
 
 0.941
hpt
Hypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.940
deoA
Thymidine phosphorylase.
 
  
 0.939
upp
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
  
 
 0.931
cdd
Cytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis; Belongs to the cytidine and deoxycytidylate deaminase family.
 
 
 0.930
xpt
Putative 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.
  
 
 0.924
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.924
SUB0241
Internal region is similar to Escherichia coli 2',3'-cyclic-nucleotide 2'-phosphodiesterase precursor CpdB UniProt:CN16_ECOLI (EMBL:ECCPDB) (647 aa) fasta scores: E()=5.6e-90, 46.809% id in 611 aa.
  
 
 0.916
SUB1410
Nicotinate phosphoribosyltransferase (NAPRTase) family protein; 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.
