What's a GeneRIF?
  1. Data indicate that protein disulfide-isomerases DsbC is involved in the protection of single cysteine residues against oxidative stress.
    Title: A new role for Escherichia coli DsbC protein in protection against oxidative stress.
  2. Our data reveal that the conserved plasmid-encoded DsbP protein is a bona fide disulfide isomerase and suggest that a dedicated oxidative folding enzyme is important for conjugative plasmid transfer.
    Title: The multidrug resistance IncA/C transferable plasmid encodes a novel domain-swapped dimeric protein-disulfide isomerase.
  3. DsbC either prevents the formation of these mixed disulphides or resolves these adducts subsequently. In the process, DsbC itself gets oxidized and proceeds to catalyse disulphide bond formation.
    Title: Overexpression of the rhodanese PspE, a single cysteine-containing protein, restores disulphide bond formation to an Escherichia coli strain lacking DsbA.
  4. Crystal structure of the outer membrane protein RcsF, a new substrate for the periplasmic protein-disulfide isomerase DsbC

  5. Data found that the periplasmic disulfide isomerase DsbC cooperates with SurA and the thiol oxidase DsbA in the folding of the essential beta-barrel protein LptD.
    Title: The protein-disulfide isomerase DsbC cooperates with SurA and DsbA in the assembly of the essential β-barrel protein LptD.

  7. study found that DsbG & DsbC control the global sulfenic acid content of the periplasm & protect single cysteine residues from oxidation; DsbG interacts with the YbiS protein and, along with DsbC, regulates oxidation of its catalytic cysteine residue

  8. The data indicate that DsbC can assist DsbA in a DsbD-independent manner to oxidatively fold envelope proteins.
