Essay

The functional diversity in proteins, although mediated by sophisticated tertiary and quaternary structures, relies on a small set of distinct secondary structural elements: sheets, helices and turns. Search for new nonnatural oligomers ("foldamers") designed to reproduce or mimic the essential protein features have gained considerable interest with potential application in pharmaceutical research. Seminal works published by the groups of Seebach, Gellman and Hanessian have revealed that short peptides made exclusively with enantiopure b- or g-amino acids, correctly substituted, could form stable helical or pleated-sheet-type structures in solution and in the solid state.
