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

udkUridine kinase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme. (211 aa)    
Predicted Functional Partners:
upp
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
 
 0.998
cmk
Cytidylate kinase; Evidence 1a: Function experimentally demonstrated in the studied strain; enzyme.
   
 
 0.981
yrrO
Putative hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the peptidase U32 family.
  
    0.975
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP, with ATP or dATP as the most efficient phosphate donors. Is also able to phosphorylate 5-fluoro-UMP and 6-aza-UMP.
   
 
 0.958
pyrF
Orotidine 5'-phosphate decarboxylase; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP); Belongs to the OMP decarboxylase family. Type 1 subfamily.
  
 0.948
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.
   
 
 0.941
cdd
Cytidine/deoxycytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
    
 0.939
pdp
Pyrimidine-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.
    
 0.938
yfkN
Exported 2',3'-cyclic-nucleotide 2'-phosphodiesterase, 2' (or 3') nucleotidase and 5' nucleotidase; Catalyzes the release of inorganic phosphate from 2',3'- cyclic nucleotides through consecutive 2',3'-phosphodiesterase and 3'- (or 2') nucleotidase activities. Also possesses a 5'-nucleotidase activity. Does not catalyze the release of inorganic phosphate from 3',5'-cyclic nucleotides. Probably plays a role in the cellular reprocessing of nucleotides present in the medium, under conditions of phosphate shortage.
 
 
 0.921
yrrN
Putative hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the peptidase U32 family.
