Although scientists have endeavored for the last three decades, only a few new antimicrobials are approved by the FDA. I have initiated and led a research program that focused on the interrogation of a transporter of capsular polysaccharides Wza that is conserved in Gram-negative bacteria. Protein engineering of Wza enabled the application of single-molecule electrical channel recording to screen for blockers and understand the bi-molecular interactions at the single-molecule level. Cyclic oligosaccharide am<sub>8<\/sub>\u03b3CD that binds to the barrel of Wza with nanomolar affinity was discovered. It is non-toxic to the bacteria but it enhances the vulnerability of bacteria to immune attacks by removing the protective capsule layer. A combination of this inhibitor and a synthetic glycoconjugate vaccine based on the lipopolysaccharide has resulted in better immune clearance of bacteria from attacking the host cells. To enable the continual discovery of next-generation of Wza inhibitors, an advanced multidisciplinary single-molecule platform to study the interaction of Wza and its natural substrate K30 polysaccharide fragments has also been established. Furthermore, a novel approach to create monodisperse transmembrane alpha-helical peptide barrels has been developed, based on the C-terminal D4 domain of Wza. Overall, a combination of chemistry, biochemistry, single-molecule biophysics, biology, computation, etc. has been proven a useful and efficient approach to discover novel therapeutics and develop novel biotechnologies.<\/p>\n<div class=\"page\" title=\"Page 1\">\n<div class=\"section\">\n<div class=\"layoutArea\">\n<div class=\"column\">\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-231\" src=\"wp\/wp-content\/uploads\/2019\/07\/seminar11-709x1024.png\" alt=\"\" width=\"640\" height=\"924\" srcset=\"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/wp\/wp-content\/uploads\/2019\/07\/seminar11-709x1024.png 709w, https:\/\/www.ag.kagawa-u.ac.jp\/abc\/wp\/wp-content\/uploads\/2019\/07\/seminar11-208x300.png 208w, https:\/\/www.ag.kagawa-u.ac.jp\/abc\/wp\/wp-content\/uploads\/2019\/07\/seminar11-768x1109.png 768w, https:\/\/www.ag.kagawa-u.ac.jp\/abc\/wp\/wp-content\/uploads\/2019\/07\/seminar11-187x270.png 187w, https:\/\/www.ag.kagawa-u.ac.jp\/abc\/wp\/wp-content\/uploads\/2019\/07\/seminar11.png 1125w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u6f14\u984c \u300cMultidisciplinary interrogation of g <a href=\"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/?p=230\" class=\"read-more\">Read More &#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":231,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"_locale":"ja","_original_post":"230","footnotes":""},"categories":[5],"tags":[],"class_list":["post-230","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-5","ja"],"_links":{"self":[{"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/posts\/230","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=230"}],"version-history":[{"count":2,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/posts\/230\/revisions"}],"predecessor-version":[{"id":261,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/posts\/230\/revisions\/261"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=\/wp\/v2\/media\/231"}],"wp:attachment":[{"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=230"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=230"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ag.kagawa-u.ac.jp\/abc\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=230"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
