Recombinant Disulfide Oxidoreductase (rDsbA), produced from E. coli is a periplasmic protein and thioredoxin superfamily member which introduces disulfide bonds directly into substrate proteins by donating the disulfide bond in its active-site Cys30-Pro31-His32-Cys33 to a pair of cysteines in substrate proteins. DsbA consists of 208 amino acids containing signal peptide (1-19 amino acids). Recombinant DsbA (residues 20-208) was expressed in E. coli and purified by using conventional chromatography techniques. Alternative Names: Thiol:disulfide interchange protein dsbC protein, xprA protein, Disulfide-bond isomerase (DsbC) E.Coli protein, Disulfide-bond isomerase C Thiol:disulfide interchange protein dsbC ., dsbC protein
