    GO ID   Ontology GO Term Definition
    6520   Cellular Amino Acid Metabolic Process  The Chemical Reactions and Pathways Involving Amino Acids Carboxylic Acids Containing One or More Amino Groups As Carried Out by Individual Cells. 
    9058   Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Substances; Typically the Energy Requiring Part of Metabolism in Which Simpler Substances Are Transformed Into More Complex Ones. 
    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. 
    4069   L Aspartate:2 Oxoglutarate Aminotransferase Activity  Catalysis of the Reaction: L Aspartate + 2 Oxoglutarate = Oxaloacetate + L Glutamate. 
    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.
