    GO ID   Ontology GO Term Definition
    6064   Glucuronate Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Glucuronate Any Salt or Ester of Glucuronic Acid. 
    6974   Cellular Response to DNA Damage Stimulus  Any Process That Results in a Change in State or Activity of a Cell (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Stimulus Indicating Damage to Its DNA From Environmental Insults or Errors During Metabolism. 
    42840   D Glucuronate Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of D Glucuronate the D Enantiomer of Glucuronate. 
    8198   Ferrous Iron Binding  Interacting Selectively and Non Covalently with Ferrous Iron Fe(ii). 
    8927   Mannonate Dehydratase Activity  Catalysis of the Reaction: D Mannonate = 2 Dehydro 3 Deoxy D Gluconate + 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. 
    30145   Manganese Ion Binding  Interacting Selectively and Non Covalently with Manganese (mn) Ions.
