    GO ID   Ontology GO Term Definition
    7186   G Protein Coupled Receptor Signaling Pathway  A Series of Molecular Signals That Proceeds with an Activated Receptor Promoting the Exchange of GDP For GTP On the Alpha Subunit of an Associated Heterotrimeric G Protein Complex. the GTP Bound Activated Alpha G Protein Then Dissociates From the Beta and Gamma Subunits to Further Transmit the Signal Within the Cell. the Pathway Begins with Receptor Ligand Interaction or For Basal Gpcr Signaling the Pathway Begins with the Receptor Activating Its G Protein in the Absence of an Agonist and Ends with Regulation of a Downstream Cellular Process E.g. Transcription. the Pathway Can Start From the Plasma Membrane Golgi or Nuclear Membrane (pmid:24568158 and Pmid:16902576). 
    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. 
    9253   Peptidoglycan Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Peptidoglycans Any of a Class of Glycoconjugates Found in Bacterial Cell Walls. 
    16998   Cell Wall Macromolecule Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Macromolecules That Form Part of a Cell Wall. 
    19076   Viral Release From Host Cell  The Dissemination of Mature Viral Particles From the Host Cell E.g. by Cell Lysis or the Budding of Virus Particles From the Cell Membrane. 
    19835   Cytolysis  The Rupture of Cell Membranes and the Loss of Cytoplasm. 
    42742   Defense Response to Bacterium  Reactions Triggered in Response to the Presence of a Bacterium That Act to Protect the Cell or Organism. 
    16021   Integral Component of Membrane  The Component of a Membrane Consisting of the Gene Products and Protein Complexes Having At Least Some Part of Their Peptide Sequence Embedded in the Hydrophobic Region of the Membrane. 
    30430   Host Cell Cytoplasm  The Cytoplasm of a Host Cell. 
    3796   Lysozyme Activity  Catalysis of the Hydrolysis of the Beta (1 >4) Linkages Between N Acetylmuramic Acid and N Acetyl D Glucosamine Residues in a Peptidoglycan and Between N Acetyl D Glucosamine Residues in Chitodextrins. 
    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. 
    4930   G Protein Coupled Receptor Activity  Combining with an Extracellular Signal and Transmitting the Signal Across the Membrane by Activating an Associated G Protein; Promotes the Exchange of GDP For GTP On the Alpha Subunit of a Heterotrimeric G Protein Complex. 
    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.
