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,
