International audience. Kinesin-5 motors are important for formation and maintenance of the bipolar mitotic spindle. Results: ATP binding triggers coupled conformational changes of kinesin-5 specific structural elements in the microtubulebound motor domain. Conclusion: Kinesin-5 mechanochemistry is tuned to its cellular functions. Significance: Subnanometer resolution structure determination of microtubule-bound kinesin-5s and kinetics experiments reveal the molecular basis of their motor properties and of drug inhibition.
