    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. 
    7586   Digestion  The Whole of the Physical Chemical and Biochemical Processes Carried Out by Multicellular Organisms to Break Down Ingested Nutrients Into Components That May Be Easily Absorbed and Directed Into Metabolism. 
    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. 
    5615   Extracellular Space  That Part of a Multicellular Organism Outside the Cells Proper Usually Taken to Be Outside the Plasma Membranes and Occupied by Fluid. 
    5515   Protein Binding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules). 
    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.
