DsbD is an inner membrane protein found in Gram-negative bacteria that transfers electrons from cytoplasmic thioredoxin to the periplasmic substrate proteins DsbC, DsbG and CcmG, reducing disulfide bonds in the target proteins to dithiols. DsbD consists of three domains: a periplasmic N-terminal domain, a central transmembrane domain and a periplasmic C-terminal domain.
