Amino acids are attached to their corresponding tRNAs through an ester linkage to the 3'-OH in the acceptor stem. This process is catalyzed by aminoacyl-tRNA synthetases, which recognize specific amino acids and their corresponding tRNA molecules. The aminoacyl-tRNA synthetase enzyme joins the amino acid to the tRNA molecule through a high-energy ester bond. This bond is then hydrolyzed during the process of translation, releasing the amino acid to form a peptide bond with the next amino acid in the growing polypeptide chain.
