The understanding of protein folding and assembly is of central importance for the design of proteins and enzymes with novel or improved functions. Minimalistic model systems, such as coiled-coils, provide an excellent platform to improve this understanding and to construct novel molecular devices. Along those lines, we designed a conformational switch that is composed of two coiled-coil forming peptides and a central binding epitope. In the absence of a binding partner, this switch adopts a hairpin-like conformation that opens upon receptor binding. Variation of the coiled-coil length modulates the strength of the intramolecular constraint. The two conformational states of this switch have been linked with characteristic fluorescent properties, which enables the detection of the receptor in real-time.

卷绕肽信标:用于蛋白质检测的可调构象开关。
对蛋白质折叠和组装的理解对于设计具有新颖或改良功能的蛋白质和酶至关重要。简约模型系统(例如螺旋线圈)提供了一个极好的平台,可以改善这种理解并构建新颖的分子装置。沿着这些路线,我们设计了一个构象开关,该构象开关由两个卷曲螺旋形成肽和一个中央结合表位组成。在没有结合伴侣的情况下,该开关采用发夹状构象,该构象在受体结合时打开。盘绕线圈长度的变化调节了分子内约束的强度。该开关的两个构象状态已与特征性的荧光特性相关联,从而可以实时检测受体。
