CC -!- FUNCTION: This protein lacks enzymatic activity (probably because of
CC the presence of a tyrosine instead of a histidine at residue 82).
CC -!- COFACTOR:
CC Name=Cu cation; Xref=ChEBI:CHEBI:23378; Evidence={ECO:0000250};
CC Note=Binds 1 copper ion per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- SUBUNIT: Homodimer.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the Cu-Zn superoxide dismutase family.
CC {ECO:0000305}.
