Tethered bilayer lipid membranes can be used as model platforms to host membrane proteins or membrane-active peptides, which can act as transducers in sensing applications. Here we present the synthesis and characterization of a valinomycin derivative, a depsipeptide that has been functionalized to serve as a redox probe in a lipid bilayer. In addition, we discuss the influence of the molecular structure of the lipid bilayer on its ability to host proteins. By using electrical impedance techniques as well as neutron scattering experiments, a clear correlation between the packing density of the lipids forming the membrane and its ability to host membrane proteins could be shown.
系留双层脂膜可用作承载膜蛋白或膜活性肽的模型平台,而膜蛋白或膜活性肽可作为传感应用中的传感器。在此,我们介绍了一种
缬氨霉素衍
生物的合成和表征,这种去肽经过功能化处理后可作为脂质双分子层中的氧化还原探针。此外,我们还讨论了脂质双分子层的分子结构对其承载蛋白质能力的影响。通过使用电阻抗技术和中子散射实验,可以发现形成膜的脂质的堆积密度与其承载膜蛋白的能力之间存在明显的相关性。
