{"department":[{"_id":"EM-Fac"}],"pmid":1,"abstract":[{"lang":"eng","text":"The hexameric AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis and initiates cytoplasmic maturation of the large ribosomal subunit by releasing the shuttling maturation factor Rlp24. Drg1 monomers contain two AAA-domains (D1 and D2) that act in a concerted manner. Rlp24 release is inhibited by the drug diazaborine which blocks ATP hydrolysis in D2. The mode of inhibition was unknown. Here we show the first cryo-EM structure of Drg1 revealing the inhibitory mechanism. Diazaborine forms a covalent bond to the 2′-OH of the nucleotide in D2, explaining its specificity for this site. As a consequence, the D2 domain is locked in a rigid, inactive state, stalling the whole Drg1 hexamer. Resistance mechanisms identified include abolished drug binding and altered positioning of the nucleotide. Our results suggest nucleotide-modifying compounds as potential novel inhibitors for AAA-ATPases."}],"oa":1,"date_published":"2021-06-09T00:00:00Z","oa_version":"Published Version","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"type":"journal_article","article_number":"3483","file":[{"success":1,"access_level":"open_access","file_id":"9556","content_type":"application/pdf","relation":"main_file","file_name":"2021_NatureComm_Prattes.pdf","creator":"cziletti","checksum":"40fc24c1310930990b52a8ad1142ee97","date_updated":"2021-06-15T18:55:59Z","date_created":"2021-06-15T18:55:59Z","file_size":3397292}],"publisher":"Springer Nature","article_type":"original","issue":"1","day":"09","acknowledged_ssus":[{"_id":"EM-Fac"}],"intvolume":"        12","publication_identifier":{"eissn":["2041-1723"]},"file_date_updated":"2021-06-15T18:55:59Z","language":[{"iso":"eng"}],"date_created":"2021-06-10T14:57:45Z","title":"Structural basis for inhibition of the AAA-ATPase Drg1 by diazaborine","article_processing_charge":"No","status":"public","acknowledgement":"We are deeply grateful to the late Gregor Högenauer who built the foundation for this study with his visionary work on the inhibitor diazaborine and its bacterial target.
