Abstract
SummaryDisulphides are often vital for the folding and stability of proteins. Dedicated enzymatic systems have been discovered that catalyse the formation of disulphides in the periplasm of prokaryotes. These discoveries provide compelling evidence for the actual catalysis of protein foldingin vivo.Disulphide bond formation inEscherichia coliis catalysed by at least three ‘Dsb’ proteins; DsbA, ‐B and ‐C. The DsbA protein has an extremely reactive, oxidizing disulphide which it simply donates directly to other proteins. DsbB is required for the reoxidation of DsbA. DsbC is active in disulphide rearrangements and appears to work synergistically with DsbA. The relative rarity of disulphides in cytoplasmic proteins appears to be dependent upon a disulphide‐destruction machine. One pivotal cog in this machine is thioredoxin reductase.
