Figure 1: Characterization of TubZ filaments.
From: TubZ filament assembly dynamics requires the flexible C-terminal tail
(a) Negative stain EM showing wild type CbTubZ filaments. Inset corresponds to the averaged filament and its Fourier transform. Arrow indicates a 4.8-nm longitudinal spacing between molecules. (b) Top and side views of our CbTubZ low-resolution filament versus BtTubZ filament13 filtered at a similar low-resolution level. Both filaments are 4-stranded but show different longitudinal distances between monomers and azimuthal angles. (c) AFM images of CbTubZT100A filaments, showing 2 – and 4-stranded filaments and bundles. The black line in the second image corresponds to the height profile shown in the graph. Color scale from dark to bright corresponds to 0–11 nm.
