The molecular events behind this fibril surface-mediated process remain largely inaccessible to current structural and imaging techniques. Using statistical mechanics, computer modeling, and chemical kinetics, we show that the catalytic structure of the fibril surface can be inferred from the aggregation behavior in the presence and absence of a fibril-binding inhibitor. We apply our approach to the case of Alzheimer’s A\r\n amyloid fibrils formed in the presence of proSP-C Brichos inhibitors. We find that self-replication of A\r\n fibrils occurs on small catalytic sites on the fibril surface, which are far apart from each other, and each of which can be covered by a single Brichos inhibitor.","lang":"eng"}],"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","type":"journal_article","file":[{"file_size":7699487,"date_created":"2024-02-26T08:20:00Z","success":1,"file_id":"15026","date_updated":"2024-02-26T08:20:00Z","creator":"dernst","access_level":"open_access","file_name":"2024_PNAS_Curk.pdf","content_type":"application/pdf","checksum":"5aeb65bcc0dd829b1f9ab307c5031d4b","relation":"main_file"}],"day":"13","article_processing_charge":"Yes","month":"02","date_updated":"2024-02-26T08:45:56Z","pmid":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"title":"Self-replication of Aβ42 aggregates occurs on small and isolated fibril sites","quality_controlled":"1","status":"public","related_material":{"record":[{"status":"public","relation":"research_data","id":"15027"}]},"oa_version":"Published Version","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2024-02-18T23:01:00Z","publisher":"Proceedings of the National Academy of Sciences","scopus_import":"1"}
