abstract：:Disulfide bond formation is a critical step in the folding of many secretory proteins. In bacteria, disulfide bonds are introduced by the periplasmic dithiol oxidase DsbA, which transfers its catalytic disulfide bond to folding polypeptides. Reduced DsbA is reoxidized by ubiquinone Q8, catalyzed by inner membrane quin...
