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. {ECO:0000256|ARBA:ARBA00024806}.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|PIRSR:PIRSR000238-1};
CC Note=Binds 1 FAD per subunit. {ECO:0000256|PIRSR:PIRSR000238-1};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738}.
CC -!- SIMILARITY: Belongs to the class-II pyridine nucleotide-disulfide
CC oxidoreductase family. {ECO:0000256|ARBA:ARBA00009333}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
