Membrane proteins have been reconstituted on lipid bilayers with zero mean-curvature (cubic phases or vesicles). Here we show that reconstitution of pore-forming membrane proteins can also occur on highly curved lipidic bilayers of reverse hexagonal mesophases, for which the mean-curvature is significantly different from zero. We further show that the membrane protein provides unique topological interconnectivities between the aqueous nanochannels, significantly enhancing mesophase transport properties.
膜蛋白已在具有零平均曲率(立方相或囊泡)的脂质双层上重建。在这里,我们表明,形成孔的膜蛋白也可以在反向六方中间相的高度弯曲的脂质双层上重建,其中平均曲率明显不为零。我们进一步表明,膜蛋白在水性纳米通道之间提供独特的拓扑连通性,显著增强中间相的传输性质。
