AbstractDisulfide-containing proteins are ideal models for studies of protein folding as the folding intermediates can be observed, trapped, and separated by HPLC during the folding reaction. However, regulating or analyzing the structures of folding intermediates of peptides and proteins continues to be a difficult problem. Recently, the development of several techniques in peptide chemistry and biotechnology has resulted in the availability of some powerful tools for studying protein folding in the context of the structural analysis of native, mutant proteins, and folding intermediates. In this review, recent developments in the field of disulfide-coupled peptide and protein folding are discussed, from the viewpoint of chemical and biotechnological methods, such as analytical methods for the detection of disulfide pairings, chemical methods for disulfide bond formation between the defined Cys residues, and applications of diselenide bonds for the regulation of disulfide-coupled peptide and protein folding.

Antibody Epitopes

The reactivity of a panel of 12 monoclonal antibodies raised against the human respiratory syncytial virus 22 kDa (22K) protein was tested by Western blotting with a set of 22K deletion mutants. The results obtained identified sequences in the C-terminal half of the 22K polypeptide required for integrity of most antibody epitopes, except for epitope 112, which was lost in mutants with short N-terminal deletions. This antibody, in contrast to the others, failed to immunoprecipitate the native 22K protein, indicating that the N terminus of this protein is buried in the native molecule and exposed only under the denaturing conditions of Western blotting. In addition, N-terminal deletions that abolished reactivity with monoclonal antibody 112 also inhibited phosphorylation of the 22K protein previously identified at Ser-58 and Ser-61, suggesting that the N terminus is important in regulating the 22K protein phosphorylation status, most likely as a result of its requirement for protein folding.

The paper discusses the role of local structural preferences of protein segments in the folding of proteins. First a short overview of the local, secondary structures detected in peptides, protein fragments, denatured proteins and early folding intermediates is given. Next the discussion of their role in protein folding is presented based on recent literature and data obtained in our laboratory. In conclusion it is pointed out that, during folding, local structures populated at low levels in denatured state may facilitate the crossing of the folding transition state barrier, and consequently accelerate the rate limiting step in folding. However, the data show that this effect does not follow simple rules.
