Three-dimensional reconstruction of tubulin sheets and re-investigation of microtubule surface lattice.
Sheets are incomplete microtubule walls observed as polymorphic variants of microtubule assembly. Their substructure is similar to that of microtubules, as shown by two-dimensional optical and computer reconstruction. We have extended earlier studies by computing a three-dimensional reconstruction. From a re-investigation of the surface lattice it appears that the three-start helix of microtubules is right-handed rather than left-handed.
