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"}],"article_number":"eaaw3818","_id":"8406","doi":"10.1126/sciadv.aaw3818","publisher":"American Association for the Advancement of Science","author":[{"full_name":"Felix, Jan","first_name":"Jan","last_name":"Felix"},{"first_name":"Katharina","full_name":"Weinhäupl, Katharina","last_name":"Weinhäupl"},{"first_name":"Christophe","full_name":"Chipot, Christophe","last_name":"Chipot"},{"last_name":"Dehez","first_name":"François","full_name":"Dehez, François"},{"full_name":"Hessel, Audrey","first_name":"Audrey","last_name":"Hessel"},{"full_name":"Gauto, Diego F.","first_name":"Diego F.","last_name":"Gauto"},{"last_name":"Morlot","full_name":"Morlot, Cecile","first_name":"Cecile"},{"last_name":"Abian","full_name":"Abian, Olga","first_name":"Olga"},{"last_name":"Gutsche","first_name":"Irina","full_name":"Gutsche, Irina"},{"first_name":"Adrian","full_name":"Velazquez-Campoy, Adrian","last_name":"Velazquez-Campoy"},{"id":"7B541462-FAF6-11E9-A490-E8DFE5697425","first_name":"Paul","full_name":"Schanda, Paul","orcid":"0000-0002-9350-7606","last_name":"Schanda"},{"last_name":"Fraga","first_name":"Hugo","full_name":"Fraga, Hugo"}],"intvolume":"         5","status":"public","citation":{"mla":"Felix, Jan, et al. “Mechanism of the Allosteric Activation of the ClpP Protease Machinery by Substrates and Active-Site Inhibitors.” <i>Science Advances</i>, vol. 5, no. 9, eaaw3818, American Association for the Advancement of Science, 2019, doi:<a href=\"https://doi.org/10.1126/sciadv.aaw3818\">10.1126/sciadv.aaw3818</a>.","ista":"Felix J, Weinhäupl K, Chipot C, Dehez F, Hessel A, Gauto DF, Morlot C, Abian O, Gutsche I, Velazquez-Campoy A, Schanda P, Fraga H. 2019.
