Protein attributes

Sequence length	579 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Required to facilitate the formation of correct disulfide bonds in some periplasmic proteins and for the assembly of the periplasmic c-type cytochromes. Acts by transferring electrons from cytoplasmic thioredoxin to the periplasm. This transfer involves a cascade of disulfide bond formation and reduction steps By similarity.
Catalytic activity	Protein dithiol + NAD(P)+ = protein disulfide + NAD(P)H. HAMAP MF_00399
Subcellular location	Cell inner membrane; Multi-pass membrane protein By similarity.
Sequence similarities	Belongs to the thioredoxin family. DsbD subfamily. Contains 1 thioredoxin domain.
