Inducing alpha-helices in short oligopeptides through binding by an artificial hydrophobic cavity.
Short peptides were induced into alpha-helix conformations in water through enclathration to an artificial hydrophobic cavity. Peptides with two aromatic residues showed high affinity for the host, and these intermolecular aromatic-aromatic interactions specifically drove the helical folding of short peptides.
