Ein Motor für den Gen-Transfer zwischen Bakterien

Translokationsratsche zieht DNA in die Zelle

(PresseBox) (Köln, )
Obwohl Bakterien sich asexuell fortpflanzen, können sie auch Erbgut untereinander austauschen. Der sogenannte horizontale Gentransfer stellt ein großes Problem bei Resistenzentwicklung bei Bakterien dar. Mit ihm können resistente Bakterien ihre Fähigkeit, Antibiotika zu überleben, an andere Bakterien weitergeben. Kölner Forschern ist es gelungen, einen Teil des Mechanismus aufzuklären, der den Gen-Transfer zwischen Bakterien erst möglich macht. Sie entdeckten einen molekularen Motor, der wie eine Ratsche funktioniert und erstaunlich hohe Kräfte entwickelt. Die Forschungen wurden von Christof Hepp, einem Doktoranden der Forschergruppe von Professorin Dr. Berenike Maier vom Institut für Theoretische Physik, geleitet.
