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. HAMAP MF_00399

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 HAMAP MF_00399.

Sequence similarities

Belongs to the thioredoxin family. DsbD subfamily.

Contains 1 thioredoxin domain.
