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.

Score
hisShistidyl-tRNA synthetase; Protein synthesis; tRNA aminoacylation; Belongs to the class-II aminoacyl-tRNA synthetase family. (419 aa)    
Predicted Functional Partners:
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.
   
 0.964
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.
 
 
 0.956
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.
 
 
 0.931
PAE0064
Translation initiation factor aIF-2 gamma subunit, putative; Protein synthesis; Translation factors.
  
 0.930
guaA
GMP synthetase (glutamine-hydrolysing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.915
leuS
leucyl-tRNA synthetase; Protein synthesis; tRNA aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
 
 0.884
cysS
cysteinyl-tRNA synthetase; Protein synthesis; tRNA aminoacylation.
 
 
 0.874
rpl2
Ribosomal protein L2; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.
 
 
 0.872
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.
 
 
 0.860
lysS
lysyl-tRNA synthetase; Protein synthesis; tRNA aminoacylation; Belongs to the class-II aminoacyl-tRNA synthetase family.
 
 
 0.850
