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; 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. (953 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.916
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.

leuS
PFAM: tRNA synthetases class I (I, L, M and V); Anticodon-binding domain; TIGRFAM: leucyl-tRNA synthetase, eubacterial and mitochondrial family; COGs: COG0495 Leucyl-tRNA synthetase; InterPro IPR015413:IPR013155:IPR002302; KEGG: cyj:Cyan7822_5283 leucyl-tRNA synthetase; PFAM: Valyl/Leucyl/Isoleucyl-tRNA synthetase, class I, anticodon-binding; Aminoacyl-tRNA synthetase, class I (M); PRIAM: Leucine--tRNA ligase; SPTR: Leucyl-tRNA synthetase; TIGRFAM: Leucyl-tRNA synthetase, class Ia, bacterial/mitochondrial.
  
 
0.882
alaS
alanyl-tRNA synthetase; 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.
 
  
 0.875
aspS
aspartyl-tRNA synthetase; 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); Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
 
  
 0.855
argS
arginyl-tRNA synthetase; PFAM: DALR anticodon binding domain; Arginyl tRNA synthetase N terminal domain; tRNA synthetases class I (R); TIGRFAM: arginyl-tRNA synthetase; COGs: COG0018 Arginyl-tRNA synthetase; HAMAP: Arginyl-tRNA synthetase, class Ic; InterPro IPR005148:IPR015945:IPR008909:IPR001278; KEGG: ava:Ava_3561 arginyl-tRNA synthetase; PFAM: Arginyl-tRNA synthetase, class Ic, core; Arginyl tRNA synthetase, class Ic, N-terminal; DALR anticodon binding; PRIAM: Arginine--tRNA ligase; SMART: DALR anticodon binding; SPTR: Arginyl-tRNA synthetase; TIGRFAM: Arginyl-tRNA synthetase, class Ic.

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.
  
  
 0.833
gltX
glutamyl-tRNA synthetase; 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.
  
 
 0.808
atpA
ATP synthase F1 subcomplex alpha subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.
  
  
 0.774
trpS
tryptophanyl-tRNA synthetase; Catalyzes the attachment of tryptophan to tRNA(Trp). Belongs to the class-I aminoacyl-tRNA synthetase family.
