Name:Thiol:disulfide interchange protein dsbA
Synonyms:Not Available
Gene Name:dsbA
Enzyme Class:Not Available
Biological Properties
General Function:Involved in protein disulfide oxidoreductase activity
Specific Function:Required for disulfide bond formation in some periplasmic proteins such as phoA or ompA. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbA is reoxidized by dsbB. It is required for pilus biogenesis
