    GO ID   Ontology GO Term Definition
    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. 
    42597   Periplasmic Space  The Region Between the Inner (cytoplasmic) and Outer Membrane (gram Negative Bacteria) or Cytoplasmic Membrane and Cell Wall (fungi and Gram Positive Bacteria). 
    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. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion. 
    51536   Iron Sulfur Cluster Binding  Interacting Selectively and Non Covalently with an Iron Sulfur Cluster a Combination of Iron and Sulfur Atoms. 
    51539   4 Iron 4 Sulfur Cluster Binding  Interacting Selectively and Non Covalently with a 4 Iron 4 Sulfur (4fe 4s) Cluster; This Cluster Consists of Four Iron Atoms with the Inorganic Sulfur Atoms Found Between the Irons and Acting As Bridging Ligands.
