protein structures. Herein, we report the stabilization of a remarkably short β-sheet by incorporating N-(hydroxy)glycine (Hyg) residues into the backbone of peptides. These peptide–peptoid hybrids form unique parallel β-sheet structures by self-assembly upon hydrogenation. Our spectroscopic and crystallographic data suggest that the local conformational perturbations induced by N-(hydroxy)amides are outweighed
新型和功能仿生折叠剂的设计仍然是创建天然蛋白质结构模拟物的主要挑战。本文中,我们报道了通过将N-(羟基)甘
氨酸(Hyg)残基掺入肽的骨架来显着缩短β-折叠的稳定性。这些肽-类肽杂化物通过加氢时自组装形成独特的平行β-折叠结构。我们的光谱和晶体学数据表明,由N-(羟基)酰胺引起的局部构象扰动被强链间氢键网络所抵消。
