Thiol:disulfide interchange protein

Thiol:disulfide interchange protein (DsbC) is a prokaryotic disulfide bond isomerase. DsbC acts as a proofreader and breaks the incorrectly formed disulfide bonds. It contains the CXXC motif. DsbC is activated by the N terminal domain of DsbD. DsbD transfers electrons from the cytoplasmic thioredoxin to the periplasm thus maintaining the active site of DsbC, DsbE and DsbG in a reduced state. DsbE catalyzes the reductive step in the assembly of periplasmic c-type cytochrome. DsbG provides reducing equivalents to rescue oxidatively-damaged secreted proteins.
