Abstract

Disulfide-bond formation is important for the correct folding of a great number of proteins that are exported to the cell envelope of bacteria. Bacterial cells have evolved elaborate systems to promote the joining of two cysteines to form a disulfide bond and to repair misoxidized proteins. In the past two decades, significant advances have occurred in our understanding of the enzyme systems (DsbA, DsbB, DsbC, DsbG, and DsbD) used by the gram-negative bacterium Escherichia coli to ensure that correct pairs of cysteines are joined during the process of protein folding. However, a number of fundamental questions about these processes remain, especially about how they occur inside the cell. In addition, recent recognition of the increasing diversity among bacteria in the disulfide bond-forming capacity and in the systems for introducing disulfide bonds into proteins is raising new questions. We review here the marked progress in this field and discuss important questions that remain for future studies.
