The hydrolysis of ATP causes the head of one of these proteins, which spans the "A" band of a sarcomere, to straighten.
The fastest-known processive motion is the seven-micrometer-per-second travel, via 35 nanometer steps, of the type XI of these proteins in plants. Rho kinase inactivates a phosphatase affecting these proteins, and also directly phosphorylates part of them. Most of these proteins consist of a neck next to a long coiled-coiled tail domain. Phosphorylation of the regulatory light chain of one of these proteins is important in the formation of a cleavage furrow during cytokinesis. In the absence of ATP, one of them fails to (*) unattach from its substrate, causing rigor mortis. The hydrolysis of ATP causes the head of one of these proteins, which spans the "A" band of a sarcomere, to straighten. For 10 points name this class of proteins that make up thick filaments, and are involved in muscle contraction alongside actin.
