CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875; Evidence={ECO:0000250};
CC       Note=Binds 1 Fe cation per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- INDUCTION: Expressed constitutively, although partially repressed under
CC       conditions of iron stress.
CC   -!- SIMILARITY: Belongs to the iron/manganese superoxide dismutase family.
CC       {ECO:0000305}.
