CC   -!- FUNCTION: Uses electrons from reduced NADP, by way of rubredoxin and an
CC       oxidoreductase, to catalyze the reduction of superoxide to hydrogen
CC       peroxide. {ECO:0000250}.
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:0000250|UniProtKB:P82385};
CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875; Evidence={ECO:0000250};
CC   -!- SIMILARITY: Belongs to the desulfoferrodoxin family. {ECO:0000305}.
