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:
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

hisSHistidine--tRNA ligase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme (424 aa)    
Predicted Functional Partners:
aspS
Aspartate--tRNA(Asp/Asn) ligase; 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
 
  
 0.986
lysS
Lysine--tRNA ligase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the class-II aminoacyl-tRNA synthetase family
   
 
 0.935
valS
Valine--tRNA ligase; 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). Catalyzes the attachment of valine to tRNA(Val); Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily
 
  
 0.922
leuS
Leucine--tRNA ligase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family
  
  
 0.906
pheS
Phenylalanine--tRNA ligase alpha subunit; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily
 
 
 0.904
pheT
Phenylalanine--tRNA ligase beta subunit; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily
 
  
 0.897
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)
 
 
 0.886
metS
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 2B subfamily
 
 
 0.842
ispG
4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase (flavodoxin); Converts 2C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-2,4cPP) into 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate; Belongs to the IspG family
 
  
 0.832
thrS
Threonine--tRNA ligase 1; 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
