CC -!- FUNCTION: Serves to protect the cell against DNA damage by alkyl
CC hydroperoxides. It can use either NADH or NADPH as electron donor for
CC direct reduction of redox dyes or of alkyl hydroperoxides when combined
CC with the AhpC protein.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC Note=Binds 1 FAD per subunit. {ECO:0000250};
CC -!- SUBUNIT: Homodimer.
CC -!- MISCELLANEOUS: The active site is a redox-active disulfide bond.
CC -!- SIMILARITY: Belongs to the class-II pyridine nucleotide-disulfide
CC oxidoreductase family. {ECO:0000305}.
