MHH-Forscher entdecken Geschwindigkeitskontrolle der Bakterien Molekulare Bremse reguliert Schwimmtempo

Veröffentlichung in "Cell"

(PresseBox) (Hannover, )
Viele Bakterien bewegen sich schwimmend fort - und das sogar gerichtet. So können sie dorthin gelangen, wo es viele Nährstoffe gibt. Gemeinsam mit Schweizer Wissenschaftlern um Professor Dr. Urs Jenal fanden Professor Dr. Volkhard Kaever und Diplom-Chemiker Christian Spangler von der Medizinischen Hochschule Hannover (MHH), Institut für Pharmakologie, heraus, dass die Darmbakterien Escherichia coli auch die Schwimm-Geschwindigkeit regulieren können. Sie veröffentlichten ihre Forschungsergebnisse jetzt im Wissenschaftsjournal CELL (Nr. 141, 107-116).

Bakterien schwimmen mit Hilfe von Eiweißfäden, so genannte Flagellen, die sich wie Propeller drehen. Dafür haben sie Motoren aus Eiweißstoffen in der Bakterienwand.
