Eine Flagelle für alle Fälle


Flagella-mediated motility, where propulsion is mediated by a rotating
helical filament, is a very widespread and effective means of locomotion
for numerous bacteria. Almost half of all species assemble their
filament from more than one distinct building block, the flagellin. Here
we show how bacteria may use different flagellins to build a filament
best suited for different environments and that polarly flagellated
bacteria employ a novel way of flagella-mediated motility.
