Lifesize Model Walking on stepping stones is a good analogy of myosin V action, because one can only walk on the stones, in between doesn't work. Similarly, the free myosin V head can only attach again near the actin helical repeat distance, 36 nm, because only here is the actin subunit orientation correct. Photo courtesy Rosalind Trinick.
