By studying a pair of structurally homologous cross-β amyloid fibrils, HET-s and HELLF, with a specific isotope-labeling approach and magic-angle-spinning (MAS) NMR, we have characterized the dynamic behavior of Phe and Tyr aromatic rings to show that the hydrophobic amyloid core is rigid, without any sign of \"breathing motions\" over hundreds of milliseconds at least. Aromatic residues exposed at the fibril surface have a rigid ring axis but undergo ring flips, on a variety of time scales from ns to µs. Our approach provides direct insight into hydrophobic-core motions, enabling a better evaluation of the conformational heterogeneity generated from a NMR structural ensemble of such amyloid cross-β architecture."}],"department":[{"_id":"GradSch"},{"_id":"PaSc"}],"day":"01","file":[{"date_updated":"2023-08-16T12:33:31Z","success":1,"file_id":"14072","date_created":"2023-08-16T12:33:31Z","file_size":1422445,"checksum":"7dd083ed8850faa55c34e411ed390de9","relation":"main_file","content_type":"application/pdf","creator":"dernst","access_level":"open_access","file_name":"2023_AngewChemInt_Becker.pdf"}],"license":"https://creativecommons.org/licenses/by-nc/4.0/","type":"journal_article","tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png","short":"CC BY-NC (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"date_updated":"2024-02-21T12:14:06Z","pmid":1,"month":"05","article_processing_charge":"Yes (via OA deal)"}
