{"abstract":[{"text":"Coordinated conformational transitions in oligomeric enzymatic complexes modulate function in response to substrates and play a crucial role in enzyme inhibition and activation. Caseinolytic protease (ClpP) is a tetradecameric complex, which has emerged as a drug target against multiple pathogenic bacteria. Activation of different ClpPs by inhibitors has been independently reported from drug development efforts, but no rationale for inhibitor-induced activation has been hitherto proposed. Using an integrated approach that includes x-ray crystallography, solid- and solution-state nuclear magnetic resonance, molecular dynamics simulations, and isothermal titration calorimetry, we show that the proteasome inhibitor bortezomib binds to the ClpP active-site serine, mimicking a peptide substrate, and induces a concerted allosteric activation of the complex. The bortezomib-activated conformation also exhibits a higher affinity for its cognate unfoldase ClpX. We propose a universal allosteric mechanism, where substrate binding to a single subunit locks ClpP into an active conformation optimized for chaperone association and protein processive degradation.","lang":"eng"}],"publisher":"American Association for the Advancement of Science","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"oa_version":"Published Version","publication":"Science Advances","doi":"10.1126/sciadv.aaw3818","date_updated":"2021-01-12T08:19:03Z","day":"04","extern":"1","language":[{"iso":"eng"}],"year":"2019","main_file_link":[{"url":" https://doi.org/10.1126/sciadv.aaw3818","open_access":"1"}],"publication_identifier":{"issn":["2375-2548"]},"article_type":"original","intvolume":"         5","article_number":"eaaw3818","month":"09","author":[{"full_name":"Felix, Jan","first_name":"Jan","last_name":"Felix"},{"full_name":"Weinhäupl, Katharina","last_name":"Weinhäupl","first_name":"Katharina"},{"first_name":"Christophe","last_name":"Chipot","full_name":"Chipot, Christophe"},{"last_name":"Dehez","first_name":"François","full_name":"Dehez, François"},{"full_name":"Hessel, Audrey","last_name":"Hessel","first_name":"Audrey"},{"last_name":"Gauto","first_name":"Diego F.","full_name":"Gauto, Diego F."},{"full_name":"Morlot, Cecile","last_name":"Morlot","first_name":"Cecile"},{"full_name":"Abian, Olga","first_name":"Olga","last_name":"Abian"},{"full_name":"Gutsche, Irina","first_name":"Irina","last_name":"Gutsche"},{"full_name":"Velazquez-Campoy, Adrian","first_name":"Adrian","last_name":"Velazquez-Campoy"},{"full_name":"Schanda, Paul","orcid":"0000-0002-9350-7606","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","first_name":"Paul","last_name":"Schanda"},{"first_name":"Hugo","last_name":"Fraga","full_name":"Fraga, Hugo"}],"citation":{"short":"J.
