Protein attributes

Sequence length	520 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Serves to protect the cell against DNA damage by alkyl hydroperoxides. It can use either NADH or NADPH as electron donor for direct reduction of redox dyes or of alkyl hydroperoxides when combined with the AhpC protein.
Cofactor	Binds 1 FAD per subunit By similarity.
Subunit structure	Homodimer By similarity.
Miscellaneous	The active site is a redox-active disulfide bond.
Sequence similarities	Belongs to the class-II pyridine nucleotide-disulfide oxidoreductase family.
