    GO ID   Ontology GO Term Definition
    9115   Xanthine Catabolic Process  The Chemical Reactions and Pathways Resulting in the Breakdown of Xanthine 2 6 Dihydroxypurine a Purine Formed in the Metabolic Breakdown of Guanine But Not Present in Nucleic Acids. 
    55114   Oxidation Reduction Process  A Metabolic Process That Results in the Removal or Addition of One or More Electrons to or From a Substance with or Without the Concomitant Removal or Addition of a Proton or Protons. 
    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. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5777   Peroxisome  A Small Organelle Enclosed by a Single Membrane and Found in Most Eukaryotic Cells. Contains Peroxidases and Other Enzymes Involved in a Variety of Metabolic Processes Including Free Radical Detoxification Lipid Catabolism and Biosynthesis and Hydrogen Peroxide Metabolism. 
    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. 
    4854   Xanthine Dehydrogenase Activity  Catalysis of the Reaction: Xanthine + Nad+ + H2o = Urate + Nadh + H+. 
    4855   Xanthine Oxidase Activity  Catalysis of the Reaction: Xanthine + H2o + O2 = Urate + Hydrogen Peroxide. 
    5506   Iron Ion Binding  Interacting Selectively and Non Covalently with Iron (fe) Ions. 
    8762   Udp N Acetylmuramate Dehydrogenase Activity  Catalysis of the Reaction: Udp N Acetylmuramate + Nadp+ = Udp N Acetyl 3 O (1 Carboxyvinyl) D Glucosamine + Nadph + H+. 
    9055   Electron Carrier Activity  Any Molecular Entity That Serves As an Electron Acceptor and Electron Donor in an Electron Transport Chain. an Electron Transport Chain Is a Process in Which a Series of Electron Carriers Operate Together to Transfer Electrons From Donors to Any of Several Different Terminal Electron Acceptors to Generate a Transmembrane Electrochemical Gradient. 
    16491   Oxidoreductase Activity  Catalysis of an Oxidation Reduction (redox) Reaction a Reversible Chemical Reaction in Which the Oxidation State of an Atom or Atoms Within a Molecule Is Altered. One Substrate Acts As a Hydrogen or Electron Donor and Becomes Oxidized While the Other Acts As Hydrogen or Electron Acceptor and Becomes Reduced. 
    16614   Oxidoreductase Activity Acting On Ch Oh Group of Donors  Catalysis of an Oxidation Reduction (redox) Reaction in Which a Ch Oh Group Act As a Hydrogen or Electron Donor and Reduces a Hydrogen or Electron Acceptor. 
    43546   Molybdopterin Cofactor Binding  Interacting Selectively and Non Covalently with the Molybdopterin Cofactor (moco) Essential For the Catalytic Activity of Some Enzymes E.g. Sulfite Oxidase Xanthine Dehydrogenase and Aldehyde Oxidase. the Cofactor Consists of a Mononuclear Molybdenum (mo Molybdopterin) or Tungsten Ion (w Molybdopterin) Coordinated by One or Two Molybdopterin Ligands. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion. 
    50660   Flavin Adenine Dinucleotide Binding  Interacting Selectively and Non Covalently with FAD Flavin Adenine Dinucleotide the Coenzyme or the Prosthetic Group of Various Flavoprotein Oxidoreductase Enzymes in Either the Oxidized Form FAD or the Reduced Form Fadh2. 
    51536   Iron Sulfur Cluster Binding  Interacting Selectively and Non Covalently with an Iron Sulfur Cluster a Combination of Iron and Sulfur Atoms. 
    51537   2 Iron 2 Sulfur Cluster Binding  Interacting Selectively and Non Covalently with a 2 Iron 2 Sulfur (2fe 2s) Cluster; This Cluster Consists of Two Iron Atoms with Two Inorganic Sulfur Atoms Found Between the Irons and Acting As Bridging Ligands.
