The Chemical Reactions and Pathways by Which the Various Amino Acids Become Bonded to Their Corresponding Trnas. the Most Common Route For Synthesis of Aminoacyl TRNA Is by the Formation of an Ester Bond Between the 3' Hydroxyl Group of the Most 3' Adenosine of the TRNA Usually Catalyzed by the Cognate Aminoacyl TRNA Ligase. a Given Aminoacyl TRNA Ligase Aminoacylates All Species of an Isoaccepting Group of TRNA Molecules.
Ligase Activity Forming Aminoacyl TRNA and Related Compounds
Catalysis of the Joining of an Amino Acid and a Nucleic Acid (usually Trna) or Poly(ribitol Phosphate) with the Concomitant Hydrolysis of the Diphosphate Bond in ATP or a Similar Triphosphate. the Reaction Forms an Aminoacyl TRNA or a Related Compound.
