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&#8217; 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\/wp-content\/uploads\/2023\/09\/2-2.jpg\" alt=\"\u6d3b\u52d5\u5831\u540d\u3009\u7269\u7406\u6240\u901a\u4fd7\u6f14\u8b1b\uff1aDynamic motors for bacterial flagella\" width=\"1240\" height=\"1754\" class=\"aligncenter size-full wp-image-32336\" srcset=\"https:\/newsletter.sinica.edu.tw\/wp-content\/uploads\/2023\/09\/2-2.jpg 1240w, https:\/newsletter.sinica.edu.tw\/wp-content\/uploads\/2023\/09\/2-2-212x300.jpg 212w, https:\/newsletter.sinica.edu.tw\/wp-content\/uploads\/2023\/09\/2-2-724x1024.jpg 724w, https:\/newsletter.sinica.edu.tw\/wp-content\/uploads\/2023\/09\/2-2-768x1086.jpg 768w, https:\/newsletter.sinica.edu.tw\/wp-content\/uploads\/2023\/09\/2-2-1086x1536.jpg 1086w, https:\/newsletter.sinica.edu.tw\/wp-content\/uploads\/2023\/09\/2-2-1080x1528.jpg 1080w\" sizes=\"(max-width: 1240px) 100vw, 1240px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u6642\u9593\uff1a 2023 \u5e74 9 \u6708 12 \u65e5\uff08\u661f\u671f\u4e8c\uff09 14 \u6642\u81f3 16 \u6642 \u5730\u9ede\uff1a \u672c\u9662\u7269\u7406\u7814\u7a76\u6240 1 \u6a13\u6f14\u8b1b\u5ef3  [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":32337,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[5],"tags":[],"acf":[],"_links":{"self":[{"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/posts\/32333"}],"collection":[{"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/comments?post=32333"}],"version-history":[{"count":1,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/posts\/32333\/revisions"}],"predecessor-version":[{"id":32425,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/posts\/32333\/revisions\/32425"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/media\/32337"}],"wp:attachment":[{"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/media?parent=32333"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/categories?post=32333"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/newsletter.sinica.edu.tw\/wp-json\/wp\/v2\/tags?post=32333"}],"curies":[{"name":"wp","href":"https:\/api.w.org\/{rel}","templated":true}]}}
