This entry represents the N-terminal domain of DsbD, a transmembrane electron transporter [1-3]. DsbD binds to a DsbC dimer and selectively activates it using electrons from the cytoplasm. The N-terminal domain of DsbD (DsbDN) is capable of forming disulfides with oxidized DsbC, DsbE, or DsbG as well as with reduced DsbD [1-3].	Domain
