A major question about protein folding is whether the coming together by diffusion of different segments of the polypeptide chain is rate-determining. This seemingly simple question has been very difficult to answer experimentally, but a positive res

The disulphide folding pathway of bovine pancreatic trypsin inhibitor (BPTI) revealed that the native conformation is still stable in each intermediate state with two native disulphide linkages, in the absence of each of the corresponding third disul

Proteins can fold very rapidly, undoubtedly because they do not do so simply by random searching. The stable, partly folded species that can be detected during protein refolding are, however, of uncertain kinetic significance. The available kinetic e

Proteins with the thioredoxin fold have widely differing stabilities of the disulfide bond that can be formed between the two cysteines at their active site sequence motif Cys1-Xaa2-Yaa3-Cys4. This is believed to be regulated not by varying the disul

A genetically engineered protein consisting of the 120 residues at the N-terminus of human protein disulfide isomerase (PDI) has been characterized by 1H, 13C, and 15N NMR methods. The sequence of this protein is 35% identical to Escherichia coli thi

The physical basis of the unusually low pKa values of an active site cysteine thiol group in proteins with the thioredoxin fold is unknown. The electrostatic field associated with an alpha-helix pointing with its N terminus towards the cysteine resid

The two thioredoxin-like domains of human protein disulfide isomerase (PDI) have been produced in bacteria as individual soluble, folded protein molecules, and their functional properties have been compared to those of intact PDI. The two individual

DsbC is a soluble protein of the bacterial periplasm that was identified genetically as being involved in protein disulfide formation. The gene sequence was corrected to include an additional proline residue and was then consistent with the molecular

The mechanism of action of the bacterial periplasm protein DsbA in introducing disulfide bonds into proteins was studied by its action on a model disordered peptide containing only two cysteine residues. Most of the reactions between the various thio

The crystal structure of bacteriophage P22 tailspike protein reveals a striking fold with a distinctive, fish-like appearance, and helps explain many of the properties of this unusual molecule and its folding pathway.
