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

Score
pyrHUridylate kinase (pyrH); Catalyzes the reversible phosphorylation of UMP to UDP. (217 aa)    
Predicted Functional Partners:
rps2
Protein synthesis; Ribosomal proteins: synthesis and modification; Belongs to the universal ribosomal protein uS2 family.
  
  
 0.987
upp
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
  
 
 0.981
PAE0768
Orotidine-5'-monophosphate decarboxylase (pyrF); Purines, pyrimidines, nucleosides, and nucleotides; Pyrimidine ribonucleotide biosynthesis.
 
 
 0.953
ndk
Nucleoside diphosphate kinase (ndk); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate (By similarity).
  
 
 0.949
surE1
surE stationary-phase survival protein homolog; Nucleotidase that shows the greatest phosphatase activity on purine (deoxy)nucleoside 5'-monophosphates, particularly the substrates 5'-GMP, 5'-AMP and 2'-deoxy-5'-AMP; Belongs to the SurE nucleotidase family.
 
  
 0.930
surE2
surE stationary-phase survival protein homolog; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.920
rpl1
Ribosomal protein L1; Binds directly to 23S rRNA. Probably involved in E site tRNA release.
 
  
 0.896
uppS
Conserved hypothetical protein; Catalyzes the sequential condensation of isopentenyl diphosphate (IPP) with geranylgeranyl diphosphate (GGPP) to yield (2Z,6Z,10Z,14Z,18Z,22Z,26Z,30E,34E,38E)-undecaprenyl diphosphate (tritrans,heptacis-UPP). It is probably the precursor of glycosyl carrier lipids.
  
  
 0.865
guaA
GMP synthetase (glutamine-hydrolysing); Catalyzes the synthesis of GMP from XMP.
   
  
 0.848
pyrG
CTP synthase (pyrG); Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
  
 0.828
