Protein
Thiol:disulfide interchange protein DsbD
Organism
Escherichia coli (strain K12)
Function
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.
Similarity
Belongs to the thioredoxin family. DsbD subfamily.
