Title: Atomic Structure of a Short alpha-Helix Stabilized by a Main Chain Hydrogen-Bond Surrogate

Abstract

Herein we report the 1.15 Angstroms X-ray crystal structure of a short {alpha}-helix in which the N-terminal i and i + 4 main chain hydrogen bond is replaced with a carbon-carbon bond. The structure shows that the hydrogen-bond surrogate (HBS) derived a-helix truly resembles the structure of canonical a-helices and provides unequivocal support for our helix nucleation strategy.
