CC -!- FUNCTION: Destroys superoxide anion radicals which are normally
CC produced within the cells and which are toxic to biological systems.
CC Catalyzes the dismutation of superoxide anion radicals into O2 and H2O2
CC by successive reduction and oxidation of the transition metal ion at
CC the active site. {ECO:0000250|UniProtKB:P80293}.
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 Evidence={ECO:0000250|UniProtKB:P80293};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:20697;
CC Evidence={ECO:0000250|UniProtKB:P80293};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:P80293};
CC Name=Fe(3+); Xref=ChEBI:CHEBI:29034;
CC Evidence={ECO:0000250|UniProtKB:P80293};
CC Note=Binds 1 Mn(2+) or Fe(3+) ion per subunit.
CC {ECO:0000250|UniProtKB:P80293};
CC -!- SIMILARITY: Belongs to the iron/manganese superoxide dismutase family.
CC {ECO:0000305}.
