beta-alanyl-l-phenylalanine (3), form hydrogen-bonded supramolecular double helices with a pitch length of 1 nm, whereas the C-terminally positioned beta-alanine containing dipeptide (4), l-phenylalanyl-beta-alanine, does not form a supramolecular double helical structure. beta-Ala-Xaa (Xaa = Val/Ile/Phe) can be regarded as a new motif for the formation of supramolecular double helical structures in the solid state
[结构:见文字]。一系列具有N末端β-丙氨酸残基,β-丙氨酰基-1-缬氨酸(1),β-丙氨酰基-1-异亮氨酸(2)和β-丙氨酰基的水溶性合成二肽(1-3) -l-苯丙氨酸(3)形成氢键结合的超分子双螺旋,节距长度为1 nm,而C端定位的含β-丙氨酸的二肽(4),l-苯丙氨酰基-β-丙氨酸不形成超分子双螺旋结构。β-Ala-Xaa(Xaa = Val / Ile / Phe)可以看作是固态超分子双螺旋结构形成的新基序。
