Crystal structure of the Candida albicans Kar3 kinesin motor domain fused to maltose-binding protein

► The Candida albicans Kar3 motor domain structure was solved as a maltose-binding protein fusion. ► The electrostatic surface and part of the ATPase pocket of the motor domain differs markedly from other kinesins. ► The MBP-Kar3 interface highlights a new site for intramolecular or intermolecular interactions.
