Abstract

Beta-Hairpins are important elements in protein structure,1 implicated in the nucleation of beta-sheets in protein folding.2 Multiple hairpin structures, in which successive strands are connected by very short loops (2-5 residues), are found in the trans-membrane beta-barrel structures formed by the bacterial porins.3 Considerable recent attention has been directed toward the synthesis of isolated beta-hairpins, stable in both aqueous and organic solvents.4 In most cases the central nucleating segment has a high propensity to form either type I’ or type II’ beta-turn structures, a feature that occurs widely in protein structures.1 The design of peptides that mimic folding patterns observed in proteins, from first principles, provides a rigorous test of our understanding of the factors that determine polypeptide stereochemistry.
