    6418   TRNA Aminoacylation For Protein Translation  The Synthesis of Aminoacyl TRNA by the Formation of an Ester Bond Between the 3' Hydroxyl Group of the Most 3' Adenosine of the TRNA to Be Used in Ribosome Mediated Polypeptide Synthesis. 
    6430   Lysyl TRNA Aminoacylation  The Process of Coupling Lysine to Lysyl TRNA Catalyzed by Lysyl TRNA Synthetase. in TRNA Aminoacylation the Amino Acid Is First Activated by Linkage to AMP and Then Transferred to Either the 2' or the 3' Hydroxyl Group of the 3' Adenosine Residue of the Trna.
