Fig. 2.

Structures of Eg5 and the tubulin heterodimer with the electric field lines. (A) Structures of Eg5 and tubulin at a 20 Å distance. The Eg5 motor domain is shown in orange, and α and β-tubulin are shown in blue and pink, respectively. (B) Electric field lines between the Eg5 motor domain and tubulin heterodimer. They are positioned the same as in figure (A). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
