Designing and utilization of biomimetic membrane systems generated by bottom-up processes is a rapidly growing scientific and engineering field. Elucidation of the supramolecular construction principle of archaeal cell envelopes composed of S-layer stabilized lipid membranes led to new strategies for generating highly stable functional lipid membranes at meso- and macroscopic scale. In this review, we provide a state of the art survey how S-layer proteins, lipids, and polysaccharides may be used as basic building blocks for the assembly of S-layer supported lipid membranes. These biomimetic membrane systems are distinguished by a nanopatterned fluidity, enhanced stability and longevity and thus, provide a dedicated reconstitution matrix for membrane-active peptides and transmembrane proteins. Exciting areas for application of composite S-layer membrane systems concern sensor systems involving specific membrane functions.
通过自下而上的过程生成的仿生膜系统的设计与应用是一个迅速发展的科学与工程领域。对由S层稳定化脂质膜构成的古细菌细胞膜超分子构建原理的阐明,催生了在中观和宏观尺度上生成高度稳定的功能性脂质膜的新策略。在本综述中,我们提供了一份关于S层蛋白、脂质和多糖如何用作组装S层支撑脂质膜的基本构建单元的最新研究概况。这些仿生膜系统具有纳米图案化的流动性、更高的稳定性和寿命,因此为膜活性肽和跨膜蛋白提供了一个专门的重组基质。复合S层膜系统令人兴奋的应用领域涉及具有特定膜功能的传感器系统。
