Abstract
Nanodiscs are protein-lipid particles that furnish a nanometer-sized membrane environment for the investigation of membrane proteins. Nanodiscs assemble spontaneously upon the removal of cholate from an initial mixture of cholate, lipids, and engineered amphipathic proteins. A combined experimental-computational approach is applied here to study the disassembly of nanodiscs through the addition of cholate to preformed particles. For this purpose, small-angle X-ray scattering experiments and coarse-grained molecular dynamics simulations were performed and compared. The study offers a detailed view of nanodisc dynamics.
