    GO ID   Ontology GO Term Definition
    42545   Cell Wall Modification  The Series of Events Leading to Chemical and Structural Alterations of an Existing Cell Wall That Can Result in Loosening Increased Extensibility or Disassembly. 
    45490   Pectin Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Pectin a Polymer Containing a Backbone of Alpha 1 4 Linked D Galacturonic Acid Residues. 
    71555   Cell Wall Organization  A Process That Results in the Assembly Arrangement of Constituent Parts or Disassembly of the Cell Wall the Rigid or Semi Rigid Envelope Lying Outside the Cell Membrane of Plant Fungal and Most Prokaryotic Cells Maintaining Their Shape and Protecting Them From Osmotic Lysis. 
    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. 
    5618   Cell Wall  The Rigid or Semi Rigid Envelope Lying Outside the Cell Membrane of Plant Fungal Most Prokaryotic Cells and Some Protozoan Parasites Maintaining Their Shape and Protecting Them From Osmotic Lysis. in Plants It Is Made of Cellulose and Often Lignin; in Fungi It Is Composed Largely of Polysaccharides; in Bacteria It Is Composed of Peptidoglycan; in Protozoan Parasites Such As Giardia Species It's Made of Carbohydrates and Proteins. 
    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. 
    30599   Pectinesterase Activity  Catalysis of the Reaction: Pectin + N H2o = N Methanol + Pectate. 
    45330   Aspartyl Esterase Activity  Catalysis of the Hydrolysis of an Ester Bond by a Mechanism Involving a Catalytically Active Aspartic Acid Residue.
