Dynamic stiffening of the flagellar hook
WebJul 7, 2013 · Rather, we find through direct measurements of the flagellar motion that a dynamic stiffening of the hook occurs during swimming (Supplementary Information S5 and Movies S5 and S6). WebBy using a light-activated proton pump as a spatially and temporally modulatable source, and the bacterial flagellar motor as a local electro-mechanical gauge, we both perturb and probe the PMF on single cells. Using global perturbations, we resolve temporal dynamics on the ms time scale and observe an asymmetrical capacitive response of the ...
