molecular function
    GO:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0016491    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.
    GO:0050605    superoxide reductase activity    Catalysis of the reaction: superoxide + reduced rubredoxin + 2 H+ = H2O2 + rubredoxin.
biological process
    GO:0098869    cellular oxidant detoxification    Any process carried out at the cellular level that reduces or removes the toxicity superoxide radicals or hydrogen peroxide.
    GO:0055114    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.
