    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. 
    19619   Protocatechuate Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown 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. 
    16787   Hydrolase Activity  Catalysis of the Hydrolysis of Various Bonds E.g. C O C N C C Phosphoric Anhydride Bonds Etc. Hydrolase Is the Systematic Name For Any Enzyme of EC Class 3. 
    47554   2 Pyrone 4 6 Dicarboxylate Lactonase Activity  Catalysis of the Reaction: 2 Oxo 2h Pyran 4 6 Dicarboxylate + H(2)o = 4 Carboxy 2 Hydroxyhexa 2 4 Dienedioate + H(+).
