    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. 
    9234   Menaquinone Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Any of the Menaquinones. Structurally Menaquinones Consist of a Methylated Naphthoquinone Ring Structure and Side Chains Composed of a Variable Number of Unsaturated Isoprenoid Residues. Menaquinones That Have Vitamin K Activity and Are Known As Vitamin K2. 
    287   Magnesium Ion Binding  Interacting Selectively and Non Covalently with Magnesium (mg) Ions. 
    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. 
    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. 
    16836   Hydro Lyase Activity  Catalysis of the Cleavage of a Carbon Oxygen Bond by Elimination of Water. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
