Protein folding guides disulfide bond formation.
The Anfinsen principle that the protein sequence uniquely determines its structure is based on experiments on oxidative refolding of a protein with disulfide bonds. The problem of how protein folding drives disulfide bond formation is poorly understood. Here, we have solved this long-standing problem by creating a general method for implementing the chemistry of disulfide bond formation and rup...
متن کاملRapid formation of the native 14-38 disulfide bond in the early stages of BPTI folding.
Using recombinant variants of BPTI, we have determined the rate constants corresponding to formation of each of the fifteen possible disulfide bonds in BPTI, starting from the reduced, unfolded protein. The 14-38 disulfide forms faster than any of the other 14 possible disulfides. This faster rate results from significantly higher intrinsic chemical reactivities of Cys-14 and Cys-38, in additio...
متن کاملDisulfide bond formation during the folding of influenza virus hemagglutinin
To study the importance of individual sulfhydryl residues during the folding and assembly in vivo of influenza virus hemagglutinin (HA), we have constructed and expressed a series of mutant HA proteins in which cysteines involved in three disulfide bonds have been substituted by serine residues. Investigations of the structure and intracellular transport of the mutant proteins indicate that (a)...

15 صفحه اولEvidence for intramolecular disulfide bond shuffling in the folding of mutant human lysozyme.
Our previous results using the Saccharomyces cerevisiae secretion system suggest that intramolecular exchange of disulfide bonds occurs in the folding pathway of human lysozyme in vivo (Taniyama, Y., Yamamoto, Y., Kuroki, R., and Kikuchi, M. (1990) J. Biol. Chem. 265, 7570-7575). Here we report on the results of introducing an artificial disulfide bond in mutants with 2 cysteine residues substi...
