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

lysSlysine--tRNA ligase; COG: COG1190; Pfam: PF01336,PF00152; InterPro: IPR002313; Belongs to the class-II aminoacyl-tRNA synthetase family. (572 aa)    
Predicted Functional Partners:
metG
methionine--tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
 
 0.985
gltX
glutamate--tRNA ligase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu); Belongs to the class-I aminoacyl-tRNA synthetase family. Glutamate--tRNA ligase type 1 subfamily.
 
 
 0.981
proS
proline--tRNA ligase; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro).
  
 0.975
argS
arginine--tRNA ligase; COG: COG0018; Pfam: PF03485,PF00750,PF05746; InterPro: IPR001278.
  
 0.973
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.
  
 0.972
leuS
leucine--tRNA ligase; COG: COG0495; Pfam: PF09334,PF00133,PF08264; InterPro: IPR002302; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 0.968
glnS
glutamine--tRNA ligase; COG: COG0008; Pfam: PF00749,PF03950; InterPro: IPR000924.
  
 
 0.967
guaA
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
  
 0.960
rpsB
Ribosomal protein S2; COG: COG0052; Pfam: PF00318; InterPro: IPR005706; Belongs to the universal ribosomal protein uS2 family.
  
 
 0.906
prs
Ribose-phosphate diphosphokinase; COG: COG0462; Pfam: PF00156; InterPro: IPR005946.
  
 
 0.896
