Protein attributes

Sequence length	236 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Acts as a disulfide isomerase, interacting with incorrectly folded proteins to correct non-native disulfide bonds. 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. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbC is reoxidized by DsbD. Ref.9
Subunit structure	Homodimer.
Subcellular location	Periplasm Ref.5.
Sequence similarities	Belongs to the thioredoxin family. DsbC subfamily. Contains 1 thioredoxin domain.
