CC ChEBI:CHEBI:18421; EC=1.15.1.1;
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Note=Binds 1 Fe cation per subunit.;
CC -!- SUBUNIT: Homotetramer at high temperature; homodimer at room
CC temperature.
CC -!- SUBCELLULAR LOCATION: Cytoplasm.
CC -!- SIMILARITY: Belongs to the iron/manganese superoxide dismutase family.
CC {ECO:0000305}.
