    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. 
    51603   Proteolysis Involved in Cellular Protein Catabolic Process  The Hydrolysis of a Peptide Bond or Bonds Within a Protein As Part of the Chemical Reactions and Pathways Resulting in the Breakdown of a Protein by Individual Cells. 
    42597   Periplasmic Space  The Region Between the Inner (cytoplasmic) and Outer Membrane (gram Negative Bacteria) or Cytoplasmic Membrane and Cell Wall (fungi and Gram Positive Bacteria). 
    71575   Integral Component of External Side of Plasma Membrane  The Component of the Plasma Membrane Consisting of the Gene Products That Penetrate Only the External Side of the Membrane. 
    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. 
    42802   Identical Protein Binding  Interacting Selectively and Non Covalently with an Identical Protein or Proteins.
