    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. 
    7596   Blood Coagulation  The Sequential Process in Which the Multiple Coagulation Factors of the Blood Interact Ultimately Resulting in the Formation of an Insoluble Fibrin Clot; It May Be Divided Into Three Stages: Stage 1 the Formation of Intrinsic and Extrinsic Prothrombin Converting Principle; Stage 2 the Formation of Thrombin; Stage 3 the Formation of Stable Fibrin Polymers. 
    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. 
    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).

    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). 
    5509   Calcium Ion Binding  Interacting Selectively and Non Covalently with Calcium Ions (ca2+).
