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

valSvalyl-tRNA synthetase (valS); 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. (874 aa)    
Predicted Functional Partners:
ileS
isoleucyl-tRNA synthetase (ileS); 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.

leuS
leucyl-tRNA synthetase (leuS); Similar to GB:L42023 SP:P43827 PID:1006043 PID:1221027 PID:1205168 percent identity: 45.93; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
0.928
rpoBC
DNA-directed RNA polymerase, beta subunit (rpoB); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
  
 0.921
alaS
alanyl-tRNA synthetase (alaS); 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.
 
  
 0.920
guaA
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
  
  
 0.910
ffh
Signal recognition particle protein (ffh); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Interaction with FtsY leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual co [...]

thrS
threonyl-tRNA synthetase (thrS); Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). Also edits incorrectly charged L-seryl-tRNA(Thr).
 
  
 0.884
aspS
aspartyl-tRNA synthetase (aspS); Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Is 1.7 times more efficient at aminoacylating tRNA(Asp) over 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).

argS
arginyl-tRNA synthetase (argS); Similar to SP:P35868 GB:Z21501 SP:P41253 GB:X54740 PID:433534 percent identity: 35.82; identified by sequence similarity; putative.

glyS
glycyl-tRNA synthetase, beta subunit (glyS); Similar to GB:L42023 SP:P43822 PID:1006049 PID:1221030 PID:1205171 percent identity: 33.58; identified by sequence similarity; putative.
