Viele Bakterien bewegen sich mithilfe langer, dünner Filamente fort. Diese sogenannten Flagellen sind bis zu zehnmal länger als die Bakterien selbst und dienen als Antrieb, indem sie in Rotation versetzt werden. So können Bakterien zum Beispiel einer Nahrungsquelle entgegenschwimmen oder zu Zellen menschlicher Schleimhäute gelangen, um sie zu infizieren. Somit dienen Flagellen auch als Werkzeuge in Infektionsprozessen und eignen sich als mögliche Angriffspunkte für neue Wirkstoffe gegen krankheitserregende Bakterien. Wie Flagellen genau aufgebaut werden und an welchen Stellen sich dieser Vorgang stören ließe, war bislang nicht bekannt. Wissenschaftler vom Helmholtz-Zentrum für Infektionsforschung (HZI) in Braunschweig haben den Mechanismus nun in Sappalhx-Kvoaeycrcepvk zbrhycclbr.
