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

Score
hisShistidyl-tRNA synthetase; Protein synthesis; tRNA aminoacylation; Belongs to the class-II aminoacyl-tRNA synthetase family. (419 aa)    
Predicted Functional Partners:
hisG
ATP phosphoribosyltransferase (hisG); Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
 
 
 0.943
eif2a
Translation initiation factor aIF-2 alpha subunit; eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. Belongs to the eIF-2-alpha family.
   
 0.930
thrS
threonyl-tRNA synthetase; 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); Belongs to the class-II aminoacyl-tRNA synthetase family.
 
 
 0.886
guaA
GMP synthetase (glutamine-hydrolysing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.886
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 (By similarity); Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 2 subfamily.
 
 
 0.844
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.
 
 
 0.811
cysS
cysteinyl-tRNA synthetase; Protein synthesis; tRNA aminoacylation.
 
  
 0.808
PAE2317
alanyl-tRNA synthetase related protein; Protein synthesis; tRNA aminoacylation.
 
 
 0.802
PAE1554
Saccharopine dehydrogenase, conjectural; Amino acid biosynthesis; Aspartate family.
       0.798
infB
Translation initiation factor IF-2 (infB), putative; Function in general translation initiation by promoting the binding of the formylmethionine-tRNA to ribosomes. Seems to function along with eIF-2.
 
 
 0.796
