Definition

Enzyme that activates an amino acid for translation by forming an aminoacyladenylate intermediate and then links this activated amino acid to the corresponding tRNA molecule (amino acid-tRNA, aminoacyl-tRNA). In general, a specific aminoacyl-tRNA synthase is available for each amino acid.

Synonyms

  • Amino acid translase
  • Aminoacyl-tRNA ligase
  • Aminoacyl-tRNA synthase
