Lipid Dynamics and Phase Transition within α-Synuclein Amyloid Fibrils

Abstract

-glycero-3-phospho-L-serine. Our results show that these lipids coassemble with α-synuclein molecules to give thin and curly amyloid fibrils. The coassembly leads to slower and more isotropic reorientation of lipid molecular segments and a decrease in both the temperature and enthalpy of the lipid chain-melting compared with those in the protein-free lipid lamellar phase. These findings provide new insights into the properties of lipids within protein-lipid assemblies that can be associated with Parkinson's disease.
