    Chain A
    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. 
    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. 
    4252   Serine Type Endopeptidase Activity  Catalysis of the Hydrolysis of Internal Alpha Peptide Bonds in a Polypeptide Chain by a Catalytic Mechanism That Involves a Catalytic Triad Consisting of a Serine Nucleophile That Is Activated by a Proton Relay Involving an Acidic Residue (e.g. Aspartate or Glutamate) and a Basic Residue (usually Histidine). 
    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. 
    8236   Serine Type Peptidase Activity  Catalysis of the Hydrolysis of Peptide Bonds in a Polypeptide Chain by a Catalytic Mechanism That Involves a Catalytic Triad Consisting of a Serine Nucleophile That Is Activated by a Proton Relay Involving an Acidic Residue (e.g. Aspartate or Glutamate) and a Basic Residue (usually Histidine). 
    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.
