been shown to form unique hydrogen-bonding patterns in protein crystal structures. Peptides were designed to mimic these patterns by forming the 6 + 10 and the 9 + 10 hydrogen-bonded rings. Factors that contribute to the formation of SP turns include controlling backbone flexibility and amino acid chirality along with creating a hydrophobic environment around the intramolecular hydrogen bonds.
丝氨酸-脯氨酸(SP)二肽基序已显示出在蛋白质晶体结构中形成独特的氢键模式。肽被设计为通过形成6 + 10和9 + 10氢键合环来模拟这些模式。促成SP转角形成的因素包括控制骨架柔性和氨基酸手性以及在分子内氢键周围形成疏水环境。
