    GO ID   Ontology GO Term Definition
    4784   Superoxide Dismutase Activity  Catalysis of the Reaction: 2 Superoxide + 2 H+ = O2 + Hydrogen Peroxide. 
    16151   Nickel Cation Binding  Interacting Selectively and Non Covalently with Nickel (ni) Cations. 
    16209   Antioxidant Activity  Inhibition of the Reactions Brought About by Dioxygen (o2) or Peroxides. Usually the Antioxidant Is Effective Because It Can Itself Be More Easily Oxidized Than the Substance Protected. the Term Is Often Applied to Components That Can Trap Free Radicals Thereby Breaking the Chain Reaction That Normally Leads to Extensive Biological Damage.
