    GO ID   Ontology GO Term Definition
    6412   Translation  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. 
    6419   Alanyl TRNA Aminoacylation  The Process of Coupling Alanine to Alanyl TRNA Catalyzed by Alanyl 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. 
    6450   Regulation of Translational Fidelity  Any Process That Modulates the Ability of the Translational Apparatus to Interpret the Genetic Code. 
    43039   TRNA Aminoacylation  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. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    49   TRNA Binding  Interacting Selectively and Non Covalently with Transfer Rna. 
    166   Nucleotide Binding  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. 
    2161   Aminoacyl TRNA Editing Activity  The Hydrolysis of an Incorrectly Aminoacylated Trna. 
    3676   Nucleic Acid Binding  Interacting Selectively and Non Covalently with Any Nucleic Acid. 
    3723   RNA Binding  Interacting Selectively and Non Covalently with an RNA Molecule or a Portion Thereof. 
    4812   Aminoacyl TRNA Ligase Activity  Catalysis of the Formation of Aminoacyl TRNA From ATP Amino Acid and TRNA with the Release of Diphosphate and Amp. 
    4813   Alanine TRNA Ligase Activity  Catalysis of the Reaction: ATP + L Alanine + Trna(ala) = AMP + Diphosphate + L Alanyl Trna(ala). 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16874   Ligase Activity  Catalysis of the Joining of Two Substances or Two Groups Within a Single Molecule with the Concomitant Hydrolysis of the Diphosphate Bond in ATP or a Similar Triphosphate. 
    16876   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. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
