This is the N-terminal domain of the disulfide bond isomerase DsbC. The whole molecule is V-shaped, where each arm is a DsbC monomer of two domains linked by a hinge; and the N-termini of each monomer join to form the dimer interface at the base of the V, so are vital for dimerisation [1]. DsbC is required for disulfide bond formation and functions as a disulfide bond isomerase during oxidative protein-folding in bacterial periplasm. It also has chaperone activity [2].

This entry represents the thioredoxin domain, which is found in proteins from all the kingdoms of living organisms. It functions as a general protein disulphide oxidoreductase. It contains a cis-proline located in a loop preceding beta-strand 4, which makes contact with the active site cysteines, and is important for stability and function. It shows a beta-sheet sandwiched between alpha-helices [11-12].
