Two kinesin motors moving along a microtubule – Image: M. Brunnbauer/TUM

Two kinesin motors moving along a microtubule (gray): the heads of one kinesin (red) have a longer range than the other (blue). A greater range between the heads allows "lane change" between the individual fibers (protofilaments) of the microtubule and results in a spiraling movement of the motor on the microtubule. A shorter range of the heads results in a straight movement of the motor. The "traces" of the two engines are different from the transparent balls of each color illustrated.
