Fig. 9.

Occupancies of hydrogen bonds above 30% at interfaces among three complexes (α-tubulin/β-tubulin, Eg5/α-tubulin, Eg5/β tubulin). (A) The occupancies of hydrogen bonds between α-tubulin and β-tubulin (left residue from α tubulin). (B) The occupancies of hydrogen bonds between the interface of the Eg5 motor domain and α-tubulin (left residue from the Eg5 motor domain). (C) The occupancies of hydrogen bonds between the interface of the Eg5 motor domain and β tubulin (left residue from the Eg5 motor domain).
