    GO ID   Ontology GO Term Definition
    6508   Proteolysis  The Hydrolysis of Proteins Into Smaller Polypeptides And/or Amino Acids by Cleavage of Their Peptide Bonds. 
    5576   Extracellular Region  The Space External to the Outermost Structure of a Cell. For Cells Without External Protective or External Encapsulating Structures This Refers to Space Outside of the Plasma Membrane. This Term Covers the Host Cell Environment Outside an Intracellular Parasite. 
    8233   Peptidase Activity  Catalysis of the Hydrolysis of a Peptide Bond. a Peptide Bond Is a Covalent Bond Formed When the Carbon Atom From the Carboxyl Group of One Amino Acid Shares Electrons with the Nitrogen Atom From the Amino Group of a Second Amino Acid. 
    8237   Metallopeptidase Activity  Catalysis of the Hydrolysis of Peptide Bonds by a Mechanism in Which Water Acts As a Nucleophile One or Two Metal Ions Hold the Water Molecule in Place and Charged Amino Acid Side Chains Are Ligands For the Metal Ions. 
    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. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
