THE DIRECTIONAL MOTION OF KINESIN BYCONFORMATIONAL COUPLING
构象耦合作用下驱动蛋白的定向运动

The conformational change of kinesin is described by the rotation of a dipole which interacts with the microtubule. The microtubule is simplified as linear distribution of dipoles. The interaction between the kinesin and the microtubule can be taken as the coupling among the dipoles. The numerical calculation shows: this coupling produces a directional motion along the microtubule and the average displacement reflects the main feature of kinesin motors.
