Spherical nanoparticle supported lipid bilayers for the structural study of membrane geometry-sensitive molecules

J Am Chem Soc. 2015 Nov 11;137(44):14031-14034. doi: 10.1021/jacs.5b08303. Epub 2015 Oct 28.

Abstract

Many essential cellular processes including endocytosis and vesicle trafficking require alteration of membrane geometry. These changes are usually mediated by proteins that can sense and/or induce membrane curvature. Using spherical nanoparticle supported lipid bilayers (SSLBs), we characterize how SpoVM, a bacterial development factor, interacts with differently curved membranes by magic angle spinning solid-state NMR. Our results demonstrate that SSLBs are an effective system for structural and topological studies of membrane geometry-sensitive molecules.
