CC   -!- FUNCTION: Destroys superoxide anion radicals which are normally
CC       produced within the cells and which are toxic to biological
CC       systems.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H(+) + 2 superoxide = H2O2 + O2; Xref=Rhea:RHEA:20696,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240,
CC         ChEBI:CHEBI:18421; EC=1.15.1.1;
CC   -!- COFACTOR:
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC       Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Evidence={ECO:0000250};
CC       Note=Binds 1 Mn(2+) or Fe(2+) ion per subunit. {ECO:0000250};
CC   -!- SIMILARITY: Belongs to the iron/manganese superoxide dismutase
CC       family. {ECO:0000305}.
