Thiol:disulfide interchange protein DsbA

Gene

dsbA

Organism
Shigella flexneri
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.
