dsbG, Thiol:disulfide interchange protein DsbG
Also Known as
DSBG_ECOLI, dsbG, ybdP
Involved in disulfide bond formation. DsbG and DsbC are part of a periplasmic reducing system that controls the level of cysteine sulfenylation, and provides reducing equivalents to rescue oxidatively damaged secreted proteins such as ErfK, YbiS and YnhG. Probably also functions as a disulfide isomerase with a narrower substrate specificity than DsbC. DsbG is maintained in a reduced state by DsbD. Displays chaperone activity in both redox states in vitro. Homodimer. Interacts with ErfK, YbiS and YnhG.
