CC -!- FUNCTION: Destroys radicals which are normally produced within the
CC cells and which are toxic to biological systems.
CC -!- FUNCTION: May confer survival advantage by accelerating dismutation of
CC superoxide of environmental origin to hydrogen peroxide, disruptive to
CC the normal mucociliary clearance process in the host.
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=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}.
