    GO ID   Ontology GO Term Definition
    8152   Metabolic Process  The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation. 
    8652   Cellular Amino Acid Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Amino Acids Organic Acids Containing One or More Amino Substituents. 
    9081   Branched Chain Amino Acid Metabolic Process  The Chemical Reactions and Pathways Involving Amino Acids Containing a Branched Carbon Skeleton Comprising Isoleucine Leucine and Valine. 
    9082   Branched Chain Amino Acid Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Amino Acids Containing a Branched Carbon Skeleton Comprising Isoleucine Leucine and Valine. 
    9097   Isoleucine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Isoleucine (2r* 3r*) 2 Amino 3 Methylpentanoic Acid. 
    9098   Leucine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Leucine 2 Amino 4 Methylpentanoic Acid. 
    9099   Valine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Valine 2 Amino 3 Methylbutanoic Acid. 
    3824   Catalytic Activity  Catalysis of a Biochemical Reaction At Physiological Temperatures. in Biologically Catalyzed Reactions the Reactants Are Known As Substrates and the Catalysts Are Naturally Occurring Macromolecular Substances Known As Enzymes. Enzymes Possess Specific Binding Sites For Substrates and Are Usually Composed Wholly or Largely of Protein But RNA That Has Catalytic Activity (ribozyme) Is Often Also Regarded As Enzymatic. 
    4084   Branched Chain Amino Acid Transaminase Activity  Catalysis of the Reaction: a Branched Chain Amino Acid + 2 Oxoglutarate = L Glutamate + a 2 Oxocarboxylate Derived From the Branched Chain Amino Acid. 
    8483   Transaminase Activity  Catalysis of the Transfer of an Amino Group to an Acceptor Usually a 2 Oxo Acid. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2. 
    52654   L Leucine Transaminase Activity  Catalysis of the Reaction: 2 Oxoglutarate + L Leucine = 4 Methyl 2 Oxopentanoate + L Glutamatic Acid. 
    52655   L Valine Transaminase Activity  Catalysis of the Reaction: 2 Oxoglutarate + L Valine = 3 Methyl 2 Oxobutanoic Acid + L Glutamatic Acid. 
    52656   L Isoleucine Transaminase Activity  Catalysis of the Reaction: 2 Oxoglutarate + L Isoleucine = (s) 3 Methyl 2 Oxopentanoic Acid + L Glutamic Acid.
