The X-ray structure of myosin head (S1) reveals the presence of a long alpha-helical structure that supports both the essential and the regulatory light chains. It has been proposed that small structural changes in the catalytic domain of S1 are amplified by swinging the long alpha-helix (the "lever arm") to produce approximately 11 nm steps. To probe the(More)
Cytoskeleton based molecular motors support most of the cellular movements and by consequence they are associated with a variety of human disorders. The wide functional diversity of these molecular motors is now explained by the presence of three different families: the myosin, kinesin and dynein families. Although they are functionally distinct, these(More)
