General annotation (Comments)

Function

Required for disulfide bond formation in some periplasmic proteins such as PhoA or OmpA. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbA is reoxidized by DsbB. It is required for pilus biogenesis.

Subcellular location

Periplasm.

Sequence similarities

Belongs to the thioredoxin family. DsbA subfamily.

Contains 1 thioredoxin domain.
