The use of peptides to reconstruct conformational determinants; a brief review.
In many biological processes, defined regions of proteins are involved in selective recognition. These regions can often be mimicked with peptides and are the main targets for vaccine and drug development. The authors review the use of peptides, to define and ultimately mimic defined protein regions of interest. Especially the role of the Pepscan method is emphasized. This method has been proven to be a useful and fast tool in defining protein regions of interest. It is based on the simultaneously synthesis of multiple peptides coupled to solid supports. Hundreds of peptides can be produced and tested in a relatively short period of time. With the construction of random peptide libraries in recombinant DNA systems, it is now even possible to screen for peptidic determinants without the requirement of preliminary knowledge of primary structure. Having this information, the affinity of peptides can be further enhanced with the Pepscan approach. The power of this approach will be illustrated with results from studies on the development of synthetic vaccines and hormone analogues.
