Important antibiotics such as β-lactams and glycopeptides target peptidoglycan biosynthesis. Class A penicillin-binding proteins (PBPs) are bifunctional membrane-bound peptidoglycan synthases that polymerize glycan chains and connect adjacent stem peptides by transpeptidation. How these enzymes work in their physiological membrane environment is poorly understood. Here, we developed a novel Förster resonance energy transfer-based assay to follow in real time both reactions of class A PBPs reconstituted in liposomes or supported lipid bilayers and applied this assay with PBP1B homologues from Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii in the presence or absence of their cognate lipoprotein activator. Our assay will allow unravelling the mechanisms of peptidoglycan synthesis in a lipid-bilayer environment and can be further developed to be used for high-throughput screening for new antimicrobials.","lang":"eng"}],"language":[{"iso":"eng"}],"article_processing_charge":"No","publication":"eLife","quality_controlled":"1","external_id":{"isi":["000627596400001"]},"publication_identifier":{"eissn":["2050-084X"]},"date_published":"2021-02-24T00:00:00Z","project":[{"_id":"2595697A-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Self-Organization of the Bacterial Cell","grant_number":"679239"},{"grant_number":"ALTF 2015-1163","_id":"2596EAB6-B435-11E9-9278-68D0E5697425","name":"Synthesis of bacterial cell wall"},{"name":"Reconstitution of bacterial cell wall sythesis","_id":"259B655A-B435-11E9-9278-68D0E5697425","grant_number":"LT000824/2016"}],"ec_funded":1,"status":"public","day":"24","oa":1,"oa_version":"Published Version","publication_status":"published","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"isi":1,"acknowledgement":"We thank Alexander Egan (Newcastle University) for purified proteins LpoB(sol) and LpoPPa(sol), Federico Corona (Newcastle University) for purified MepM, and Oliver Birkholz and Jacob Piehler (Department of Biology and Center of Cellular Nanoanalytics, University of Osnabru¨ ck) for their help with PBP1B reconstitution into polymer-SLBs and initial guidance on single particle tracking.
