Fig. 8.

Hydrogen bonds at the interfaces of the Eg5 motor domain and tubulin heterodimer. The average number of hydrogen bonds is shown with red lines. (A) (D) (G) Number of hydrogen bonds between α tubulin and β tubulin. (B) (E) (H) Number of hydrogen bonds between the Eg5 motor domain and α tubulin. (C) (F) (I) Number of hydrogen bonds between the Eg5 motor domain and β tubulin.
