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

KHD74932.1histidyl-tRNA synthase; Derived by automated computational analysis using gene prediction method: Protein Homology. (436 aa)    
Predicted Functional Partners:
hisG
ATP phosphoribosyltransferase; 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.
  
 0.985
glyS
glycyl-tRNA synthetase subunit beta; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.965
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.
 
  
 0.955
KHD74933.1
Hydrolase; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.861
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.
 
 
 0.804
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.798
lysS
lysyl-tRNA synthetase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
 
 0.785
thrS
threonine--tRNA ligase; Catalyzes the formation of threonyl-tRNA(Thr) from threonine and tRNA(Thr); catalyzes a two-step reaction, first charging a threonine molecule by linking its carboxyl group to the alpha-phosphate of ATP, followed by transfer of the aminoacyl-adenylate to its tRNA; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-II aminoacyl-tRNA synthetase family.
 
 
 0.781
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.
 
 
 0.775
ispG
4-hydroxy-3-methylbut-2-en-1-yl diphosphate synthase; 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.
