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

pdpPyrimidine-nucleoside phosphorylase; Catalyzes phosphorolysis of the pyrimidine nucleosides uridine, thymidine and 2'-deoxyuridine with the formation of the corresponding pyrimidine base and ribose-1-phosphate. (433 aa)    
Predicted Functional Partners:
cdd
Cytidine/deoxycytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
 
 0.999
nupC
Pyrimidine-nucleoside Na+(H+) cotransporter; Transport of the pyrimidine nucleoside uridine.
  
  
 0.995
deoC
Deoxyribose-phosphate aldolase; Catalyzes a reversible aldol reaction between acetaldehyde and D-glyceraldehyde 3-phosphate to generate 2-deoxy-D-ribose 5- phosphate.
 
 
 0.993
drm
Phosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family.
 
 
 0.987
pupG
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. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.
 
 
 0.974
upp
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
  
 
 0.961
tdk
Thymidine kinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
 
  
 0.961
pyrR
Transcriptional attenuator and uracil phosphoribosyltransferase activity; Regulates transcriptional attenuation of the pyrimidine nucleotide (pyr) operon by binding in a uridine-dependent manner to specific sites on pyr mRNA. This disrupts an antiterminator hairpin in the RNA and favors formation of a downstream transcription terminator, leading to a reduced expression of downstream genes; Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrR subfamily.
     
 0.955
deoD
Purine nucleoside phosphorylase; Cleavage of adenosine and its derivatives; Belongs to the PNP/UDP phosphorylase family.
 
 
 0.954
udk
Uridine kinase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme.
    
 0.938
