Single-crystal and solution conformations have been engineered for right-handed and left-handed β-double helices derived from a concatenation of achiral (E)-α,β-unsaturated γ-amino acids and chiral (E)-α,β-unsaturated γ-amino acids. The structural analogy of these new β-double helices with natural peptide double helices, and their ion-transport activities are also discussed.
单晶和溶液构象已被设计为右手和左手 β-双螺旋,这些螺旋源自非手性 ( E )-α,β-不饱和 γ-
氨基酸和手性 ( E )-α,β- 的串联不饱和γ-
氨基酸。还讨论了这些新的β-双螺旋与天然肽双螺旋的结构相似性及其离子传输活性。
