Release Of ADP From Myosin

Stable Identifier
Homo sapiens
Locations in the PathwayBrowser

The weak binding of the myosin head to the new site on the actin filament causes release of the inorganic phosphate produced by ATP hydrolysis, concomitantly with the tight binding of the head to actin. This release triggers the power stroke, a force-generating change in the shape during which the head regains its original conformation. In the course of the power stroke, the head loses its bound ADP, thereby returning to the start of a new cycle.
