Method: X-ray diffraction, Resolution 1.9Å Ligands: MES Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function DSBC_ECOLI 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. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMed DsbC is one of five Escherichia coli proteins required for disulfide bond formation and is thought to function as a disulfide bond isomerase during oxidative protein folding in the periplasm. DsbC is a 2 x 23 kDa homodimer and has both protein disulfide isomerase and chaperone activity. We report the 1.9 A resolution crystal structure of oxidized DsbC where both Cys-X-X-Cys active sites form disulfide bonds. The molecule consists of separate thioredoxin-like domains joined via hinged linker helices to an N-terminal dimerization domain. The hinges allow relative movement of the active sites, and a broad uncharged cleft between them may be involved in peptide binding and DsbC foldase activities.
