Original αγα tripeptides containing one β,γ-diamino acid have been synthesized and their conformation determined by extensive NMR and molecular dynamic studies. These studies revealed the presence of a C9 hydrogen bonded turn around the β,γ-diamino acid which was stabilized by bulky side chains of the preceding residue. This turn can be considered as a mimic of the well-known γ-turn.
原始的包含一个β,γ-二氨基酸的αγα三肽已被合成,并通过广泛的NMR和分子动力学研究确定了它们的构象。这些研究表明,在β,γ-二氨基酸周围存在一个C9氢键连接的转角,该转角被前一个残基的庞大侧链所稳定。这个转角可以被视为著名的γ转角的模拟。
