STRINGSTRING
cysS protein (Escherichia coli K12 MG1655) - STRING interaction network
"cysS" - Cysteine--tRNA ligase in Escherichia coli K12 MG1655
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:
some 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 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; Cysteine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation; Belongs to the class-I aminoacyl-tRNA synthetase family (461 aa)    
Predicted Functional Partners:
thrS
Threonine--tRNA ligase; 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). The rate- limiting step is amino acid activation in the presence of tRNA. The 2’-OH of the acceptor base (adenine 76, A76) of tRNA(Thr) and His-309 collaborate to transfer L-Thr to the tRNA; substitution of 2’-OH of A76 with hydrogen or fluorine decreases transfer efficiency 760 and 100-fold respectively. The zinc ion in the active site discriminates against charging of the isoster [...] (642 aa)

leuS
Leucine--tRNA ligase; Leucine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation; Belongs to the class-I aminoacyl-tRNA synthetase family (860 aa)
 
 
  0.902
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; Belongs to the class-I aminoacyl-tRNA synthetase family. MetG type 1 subfamily (677 aa)
 
   
  0.896
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) (938 aa)
 
   
  0.876
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 (951 aa)
 
   
  0.846
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) (430 aa)
 
   
  0.839
argS
Arginine--tRNA ligase; Arginine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation (577 aa)
 
 
  0.825
tyrS
Tyrosine--tRNA ligase; Catalyzes the attachment of L-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). Also mischarges tRNA(Tyr) with D-tyrosine, although Vmax is much lower (424 aa)
      
 
  0.820
ffh
Signal recognition particle protein; 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 components (453 aa)
 
   
  0.810
pheT
Phenylalanine tRNA synthetase, beta-subunit; Protein involved in tRNA aminoacylation for protein translation (795 aa)
 
   
  0.804
