Function

[DSBD_ECOLI] 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, thereby maintaining the active site of DsbC, DsbE and DsbG in a reduced state. This transfer involves a cascade of disulfide bond formation and reduction steps.[HAMAP-Rule:MF_00399] [DSBE_ECOLI] Involved in disulfide bond formation. Catalyzes a late, reductive step in the assembly of periplasmic c-type cytochromes, probably the reduction of disulfide bonds of the apocytochrome c to allow covalent linkage with the heme. Possible subunit of a heme lyase. DsbE is maintained in a reduced state by DsbD.

Publication Abstract from PubMed

DsbD from Escherichia coli transports two electrons from cytoplasmic thioredoxin to the periplasmic substrate proteins DsbC, DsbG and CcmG. DsbD consists of an N-terminal periplasmic domain (nDsbD), a C-terminal periplasmic domain, and a central transmembrane domain. Each domain possesses two cysteines required for electron transport. Herein, we demonstrate fast (3.9 x 10(5) M(-1)s(-1)) and direct disulfide exchange between nDsbD and CcmG, a highly specific disulfide reductase essential for cytochrome c maturation. We determined the crystal structure of the disulfide-linked complex between nDsbD and the soluble part of CcmG at 1.94 A resolution. In contrast to the other two known complexes of nDsbD with target proteins, the N-terminal segment of nDsbD contributes to specific recognition of CcmG. This and other features, like the possibility of using an additional interaction surface, constitute the structural basis for the adaptability of nDsbD to different protein substrates.
