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

aspSaspartyl-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). 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). (438 aa)    
Predicted Functional Partners:
gatB
Glu-tRNA amidotransferase (gatB); Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl- tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp- tRNA(Asn) or phospho-Glu-tRNA(Gln) (By similarity); Belongs to the GatB/GatE family. GatB subfamily.
 0.999
gatA
Amidase; Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu- tRNA(Gln) (By similarity).
 
 0.999
MJ_0243
Conserved hypothetical protein; Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl- tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp- tRNA(Asn) or phospho-Glu-tRNA(Gln) (By similarity); Belongs to the GatC family.
   
 0.990
metG
methionyl-tRNA synthetase (metS); Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
  
 0.984
gltX
glutamyl-tRNA synthetase (gltX); 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).
 
 
 0.973
leuS
leucyl-tRNA synthetase (leuS); Similar to SP:P26637 PID:1370340 PID:1403549 PID:3508 percent identity: 35.17; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 0.965
MJ_1554
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 42.23; identified by sequence similarity; putative.
  
 0.955
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 2 subfamily.
 
 0.948
argS
arginyl-tRNA synthetase (argS); Identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 0.941
glyS
glycyl-tRNA synthetase (glyS); Catalyzes the attachment of glycine to tRNA(Gly).
 
 
 0.907
