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

valSvaline--tRNA ligase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner. (881 aa)    
Predicted Functional Partners:
leuS
leucine--tRNA ligase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
0.942
ileS
isoleucine--tRNA ligase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 2 subfamily.
 
0.923
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.919
cysS2
cysteine--tRNA ligase; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
  
 0.901
aspS
aspartate--tRNA ligase; Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp/Asn); Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
  
  
 0.853
alaS1
alanine--tRNA ligase; Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.
  
  
 0.843
pheT
phenylalanine--tRNA ligase beta subunit; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.842
thrS
threonine--tRNA ligase; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.816
argS
arginine--tRNA ligase.
  
  
 0.799
serS
serine--tRNA ligase.
   
  
 0.747
