The Cellular Metabolic Process in Which a Protein Is Formed Using the Sequence of a Mature MRNA Molecule to Specify the Sequence of Amino Acids in a Polypeptide Chain. Translation Is Mediated by the Ribosome and Begins with the Formation of a Ternary Complex Between Aminoacylated Initiator Methionine TRNA GTP and Initiation Factor 2 Which Subsequently Associates with the Small Subunit of the Ribosome and an Mrna. Translation Ends with the Release of a Polypeptide Chain From the Ribosome.
The Process of Coupling Glutamine to Glutaminyl TRNA Catalyzed by Glutaminyl 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.
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.
Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose.
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.
