Fig. 2. Intra- and inter-dimer bends in different tubulin polymers.

Fig. 2

(a) Two dimers in a microtubule (plus-end at the top). The red box marks the lower dimer. The dashed yellow boxes indicate the monomers shown in the end-on views in (b). (b) The microtubule (green), RB3-bound structure (violet), outer (orange-red) and inner layer of the GDP tubes (blue) were aligned on the first β subunit. The bottom superposition shows the displacements due to the intra-dimer bending, and the top shows the displacements due to the inter-dimer bending. (c) Relative magnitude (arrow length) and the radial and tangential components of each bend.
