    GO ID   Ontology GO Term Definition
    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. 
    9073   Aromatic Amino Acid Family Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Aromatic Amino Acid Family Amino Acids with Aromatic Ring (phenylalanine Tyrosine Tryptophan). 
    9423   Chorismate Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of the Unsymmetrical Ether Derived From Phosphoenolpyruvate and 5 Phosphoshikimic Acid Formed As an Intermediate in the Biosynthesis of Aromatic Amino Acids and Many Other Compounds. 
    46279   Protocatechuate Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Protocatechuate the Anion of 3 4 Dihydroxybenzoic 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. 
    3855   3 Dehydroquinate Dehydratase Activity  Catalysis of the Reaction: 3 Dehydroquinate = 3 Dehydroshikimate + H(2)o. 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring.
