Cryo-electron tomography of GMPCPP MTs reveals lattice defects. (a) Longitudinal section through a three-dimensional tomographic reconstruction in which two different lattice defects are visible. Insets, transverse sections through the same MT with the position of the section relative to the polymer and their rotational average indicated in colour. These show the PF mismatches at the defects. (b) Three-dimensional rendering of examples of MTs with the near-surface MT coloured red and more distant MT surfaces coloured pink; left, an MT without a defect; middle and right, different MTs with lattice defects. |
