Background: Ispinesib is a small molecule inhibitor of Eg5 and induces neck linker docking. Results: Ispinesib binding to Eg5 induces subsequent movement of switch II. Conclusion: Conformational changes in L5 can alter the orientation of the neck linker regardless of the state of the catalytic site. Significance: L5 is a key regulator of both the catalytic site and switch II.
