Neuronal membranes are direct interacting partners of α-synuclein and play a role in fibrillogenesis by providing a charged catalytic surface, notably from anionic phospholipids. However, details are lacking regarding the impact of membrane composition and the driving forces leading to membrane anchorage and peptide structure conversion. To decipher the interplay of α-synuclein with neuronal membranes, the structure of AS71-82 was investigated in the presence of anionic model membranes. Infrared (IR) spectroscopy and solid-state nuclear magnetic resonance data show that AS71-82 adopts a perfectly in-register parallel β-sheet structure with fibrillar morphology upon interactions with anionic model membranes. IR thermotropism experiments conducted with several membrane compositions revealed that the phospholipids' phase transition induces a rearrangement of the AS71-82 β-sheet structure. In contrast, membranes are not significantly affected by the presence of AS71-82, which advocates for the amyloid fibrils to lie loosely on the membrane surface. The results bring new arguments for the lipid-sensing capabilities of AS71-82 and revealed its protofibrillar structure. The striking similarities between AS71-82 and α-synuclein make it a potential good aggregation inhibitor upon chemical modifications."xsd:string |
