Dsb proteins (DsbA, DsbB, DsbC, and DsbD) catalyze formation and isomerization of protein disulfide bonds in the periplasm of Escherichia coli. DsbC is periplasmic enzyme known as a disulfide isomerase and can convert aberrant disulfide bonds to correct ones. DsbC consists of 236 amino acids containing signal peptide (1-20 amino acids). Recombinant DsbC was expressed in E. coli and purified by using conventional chromatography techniques. Alternative Names: Disulfide oxidoreductase (DsbA) E Coli protein, DsDNA-binding protein A protein, Thiol disulfide interchange protein dsbA., dsbA protein, Disulfide oxidoreductase A periplasmic protein disulfide isomerase I protein, rpbB protein, Double-stranded DNA-binding protein protein
