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

leuSTIGRFAM: leucyl-tRNA synthetase; KEGG: ana:alr3283 leucyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family. (871 aa)    
Predicted Functional Partners:
pheT
TIGRFAM: phenylalanyl-tRNA synthetase, beta subunit; KEGG: ava:Ava_2221 phenylalanyl-tRNA synthetase beta subunit.

ileS
isoleucyl-tRNA synthetase; 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 1 subfamily.
 
0.974
metG
methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 0.967
gltX
Transcriptional regulator, Fis family; 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.
  
 0.943
proS
prolyl-tRNA synthetase; 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). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and involves dea [...]

ACC82510.1
Pyruvate flavodoxin/ferredoxin oxidoreductase domain protein; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin.
   
   0.910
tyrS
tyrosyl-tRNA synthetase; Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr); Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 2 subfamily.
 
 
 0.899
asnS
TIGRFAM: asparaginyl-tRNA synthetase; PFAM: tRNA synthetase, class II (D, K and N); nucleic acid binding, OB-fold, tRNA/helicase-type; KEGG: ava:Ava_3630 asparaginyl-tRNA synthetase.
  
 0.879
valS
valyl-tRNA synthetase; 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; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.
  
 
0.865
ligA
DNA ligase, NAD-dependent; DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA.
