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

cysSCysteine-tRNA ligase; Belongs to the class-I aminoacyl-tRNA synthetase family. (549 aa)    
Predicted Functional Partners:
RY69_1487
Cysteine synthase A.
  
 
 0.879
thrS
Threonine-tRNA ligase; Belongs to the class-II aminoacyl-tRNA synthetase family.
 
  
 0.824
valS
Valine-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.
 
  
 0.817
serS
Serine-tRNA ligase; Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L- seryl-tRNA(Sec), which will be further converted into selenocysteinyl- tRNA(Sec).
 
 
 0.812
RY69_1362
Tetracycline resistance protein TetQ.
  
 
 0.809
pheT
Phenylalanine-tRNA ligase beta subunit; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.788
leuS
Leucine-tRNA ligase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 
 0.737
argS
Arginine-tRNA ligase.
  
 
 0.706
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.
  
  
 0.694
RY69_1645
Glutamine amidotransferase Class I.
     
 0.640
