Effects of alternative side chain pairings and reverse turn sequences on antiparallel sheet structure in beta-peptide hairpins.

Abstract

[structure: see text] We describe a series of beta-peptide hexamers that allow us to explore relationships between sequence and hairpin folding. Different reverse turn segments are compared at the central two positions, and the outer residues allow a variety of interstrand side chain-side chain pairings. NMR analysis in methanol demonstrates that several… (More)
