    Chain A
    GO ID   Ontology GO Term Definition
    5975   Carbohydrate Metabolic Process  The Chemical Reactions and Pathways Involving Carbohydrates Any of a Group of Organic Compounds Based of the General Formula Cx(h2o)y. Includes the Formation of Carbohydrate Derivatives by the Addition of a Carbohydrate Residue to Another Molecule. 
    8152   Metabolic Process  The Chemical Reactions and Pathways Including Anabolism and Catabolism by Which Living Organisms Transform Chemical Substances. Metabolic Processes Typically Transform Small Molecules But Also Include Macromolecular Processes Such As DNA Repair and Replication and Protein Synthesis and Degradation. 
    16052   Carbohydrate Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Carbohydrates Any of a Group of Organic Compounds Based of the General Formula Cx(h2o)y. 
    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. 
    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. 
    4556   Alpha Amylase Activity  Catalysis of the Endohydrolysis of (1 >4) Alpha D Glucosidic Linkages in Polysaccharides Containing Three or More Alpha (1 >4) Linked D Glucose Units. 
    5509   Calcium Ion Binding  Interacting Selectively and Non Covalently with Calcium Ions (ca2+). 
    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. 
    16798   Hydrolase Activity Acting On Glycosyl Bonds  Catalysis of the Hydrolysis of Any Glycosyl Bond. 
    31404   Chloride Ion Binding  Interacting Selectively and Non Covalently with Chloride Ions (cl ). 
    43169   Cation Binding  Interacting Selectively and Non Covalently with Cations Charged Atoms or Groups of Atoms with a Net Positive Charge. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
