title: Molecular motors: the natural economy of kinesin.
abstract: Kinesin is a molecular-scale walking machine. New analyses of its mechanism indicate that each step along a microtubule consumes one ATP molecule, and that the binding and cleavage of ATP precede detachment of the molecule's 'feet'. Directional walking ensues if ATP processing occurs preferentially on one foot.
