+ | == Publication Abstract from PubMed == | ||
+ | Bacterial DsbC proteins are involved in rearranging or reducing mismatched disulfide bonds folding within the periplasm. The X-ray structure of the enzyme from Haemophilus influenzae has been solved and compared with the known structure of the Escherichia coli protein. The proteins act as V-shaped dimers with a large cleft to accommodate substrate proteins. The dimers are anchored by a small N-terminal domain, but have a flexible linker region which allows the larger C-terminal domain, with its reactive sulfhydryls, to clamp down on substrates. The overall folds are very similar, but the comparison shows a wider range of hinge motions than previously thought. The crystal packing of the H. influenzae protein allows the movement of the N-terminal domain with respect to the C-terminal domain through motions in the flexible hinge, generating high thermal parameters and unusually high anisotropy in the crystallographic data. | ||
