A flagellum consists of a bacterial flagellar motor (BFM), a hook, and a flagellar filament. The BFM is a natural rotary molecular machine that rotates at several hundred hertz driven by an electrochemical ion gradient. The motor consists of a rotor 50 nm in diameter surrounded by about 11 ion-conducting stator units, which exchange between motors and a membrane-bound pool. Bacterial flagella are dynamic, not only because they rotate and reverse, but also because some of their components exchange on a short time scale. These components\u2019 exchange may contribute to regulatory control, functional adaptation, and system repair.<\/p>\n<p>In this talk, Dr. Lo will present the current understanding of BFM and the newly emerging picture of protein complex exchange. It is necessary to replace a binary distinction between stable complexes and transient binding partners with a description of the lifetime and exchange dynamics of each individual protein associated with a complex.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1.jpg\" alt=\"Dynamic motors for bacterial flagella\" width=\"1240\" height=\"1754\" class=\"aligncenter size-full wp-image-12496\" srcset=\"https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1.jpg 1240w, https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1-212x300.jpg 212w, https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1-724x1024.jpg 724w, https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1-768x1086.jpg 768w, https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1-1086x1536.jpg 1086w, https:\/\/newsletter.sinica.edu.tw/en\/wp-content\/uploads\/2023\/09\/2-1-1080x1528.jpg 1080w\" sizes=\"(max-width: 1240px) 100vw, 1240px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Time: 14:00-16:00, Tuesday, September 12, 2023 Place: 1F Auditorium, Institute of Physics, Academia Sinica Speaker: Dr. Chien-Jung Lo (Department of Physics, National Central University) Host: Dr. Keng-Hui Lin (Institute of Physics, Academia Sinica) Website: https:\/\/www.phys.sinica.edu.tw\/lecture_detail.php?id=2761&#038;eng=T Abstract: Many species of bacteria use flagella to swim.
