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

BISU_1540histidyl-tRNA ligase. (450 aa)    
Predicted Functional Partners:
aspS
aspartyl-tRNA 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.
 
  
 0.978
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.
  
 0.945
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.
 
 
 0.855
thrS
threonyl-tRNA ligase; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
 
 0.854
argS
arginyl-tRNA ligase.
  
  
 0.726
pheT
phenylalanyl-tRNA synthetase subunit beta; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.724
lysS
lysyl-tRNA synthetase; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
 
 0.721
aroK
3-dehydroquinate synthase; Catalyzes the conversion of 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) to dehydroquinate (DHQ); Belongs to the sugar phosphate cyclases superfamily. Dehydroquinate synthase family.
  
  
 0.696
BISU_1539
DNA repair ATPase.
  
    0.695
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.
