- PubMed Abstract:
Cyclic constraints have proven to be very effective for preorganizing β-amino acid residues and thereby stabilizing β- and α/β-peptide helices, but little is known about possible preorganization effects among γ residues. Here we assess and compare the impact of cyclic preorganization of β and γ residues in the context of a specific α/β/γ-peptide helix. The results show that β residue preorganization is critical for helix stability but that γ residue preorganization is less important.
