CC -!- FUNCTION: Catalyzes the one-electron reduction of superoxide anion
CC radical to hydrogen peroxide at a nonheme ferrous iron center. Plays a
CC fundamental role in case of oxidative stress via its superoxide
CC detoxification activity. {ECO:0000256|ARBA:ARBA00024690}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 H(+) + reduced [rubredoxin] + superoxide = H2O2 + oxidized
CC [rubredoxin]; Xref=Rhea:RHEA:21324, Rhea:RHEA-COMP:10302, Rhea:RHEA-
CC COMP:10303, ChEBI:CHEBI:15378, ChEBI:CHEBI:16240, ChEBI:CHEBI:18421,
CC ChEBI:CHEBI:29033, ChEBI:CHEBI:29034; EC=1.15.1.2;
CC Evidence={ECO:0000256|ARBA:ARBA00001133};
CC -!- COFACTOR:
CC Name=Cu(2+); Xref=ChEBI:CHEBI:29036;
CC Evidence={ECO:0000256|ARBA:ARBA00001973};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|PIRSR:PIRSR604793-1};
CC Note=Binds 1 Fe(2+) ion per subunit. The iron ion 2 is coordinated via
CC four histidines and one cysteine residue.
CC {ECO:0000256|PIRSR:PIRSR604793-1};
CC -!- COFACTOR:
CC Name=Fe(3+); Xref=ChEBI:CHEBI:29034;
CC Evidence={ECO:0000256|PIRSR:PIRSR604793-1};
CC Note=Binds 1 Fe(3+) ion per subunit. The iron ion 1 is coordinated via
CC 4 cysteine residues. {ECO:0000256|PIRSR:PIRSR604793-1};
CC -!- SIMILARITY: Belongs to the desulfoferrodoxin family.
CC {ECO:0000256|ARBA:ARBA00005941}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
