A recent model for the structure of microtubules is used to interpret X-ray fiber diffraction patterns from microtubules, obtained under various conditions. The results suggest that tubulin may undergo conformational changes under conditions of reduced water-activity. Such changes could account for some of the differences in the structure of tubulin as determined by electron microscopy and X-ray diffraction.
