Abstract

Take a turn for the better: Residue-based secondary structural control for γ-turns and extended conformations is explored in hybrid oligopeptides. DFT and NMR studies on heterogeneous backbone oligomers comprising trans-β-norbornene amino acid (TNAA) and natural α-amino acid residues reveal a preferential formation of periodic inverse γ-turns in both polar and non-polar solvent media. These periodic γ-turn secondary structures are conformationally different from other known α/β-hybrid peptides.
