    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. 
    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. 
    10467   Gene Expression  The Process in Which a Gene's Sequence Is Converted Into a Mature Gene Product or Products (proteins or Rna). This Includes the Production of an RNA Transcript As Well As Any Processing to Produce a Mature RNA Product or an MRNA (for Protein Coding Genes) and the Translation of That MRNA Into Protein. Protein Maturation Is Included When Required to Form an Active Form of a Product From an Inactive Precursor Form. 
    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. 
    70145   Mitochondrial Asparaginyl TRNA Aminoacylation  The Process of Coupling Asparagine to Asparaginyl TRNA in a Mitochondrion Catalyzed by Asparaginyl 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. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    5654   Nucleoplasm  That Part of the Nuclear Content Other Than the Chromosomes or the Nucleolus. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5739   Mitochondrion  A Semiautonomous Self Replicating Organelle That Occurs in Varying Numbers Shapes and Sizes in the Cytoplasm of Virtually All Eukaryotic Cells. It Is Notably the Site of Tissue Respiration. 
    5759   Mitochondrial Matrix  The Gel Like Material with Considerable Fine Structure That Lies in the Matrix Space or Lumen of a Mitochondrion. It Contains the Enzymes of the Tricarboxylic Acid Cycle and in Some Organisms the Enzymes Concerned with Fatty Acid Oxidation. 
    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. 
    3676   Nucleic Acid Binding  Interacting Selectively and Non Covalently with Any Nucleic Acid. 
    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. 
    4815   Aspartate TRNA Ligase Activity  Catalysis of the Reaction: ATP + L Aspartate + Trna(asp) = AMP + Diphosphate + L Aspartyl Trna(asp). 
    5515   Protein Binding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules). 
    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. 
    42803   Protein Homodimerization Activity  Interacting Selectively and Non Covalently with an Identical Protein to Form a Homodimer. 
    50560   Aspartate Trna(asn) Ligase Activity  Catalysis of the Reaction: Trna(asx) + L Aspartate + ATP = Aspartyl Trna(asx) + Diphosphate + Amp.
