Figure 1
The Lymn–Taylor cycle (Lymn & Taylor, 1971BB20). A diagrammatic representation of the cross-bridge cycle: the myosin cross bridge is bound to actin in rigor 45° position `down' (1). ATP binds which leads to very fast dissociation from actin (2). The hydrolysis of ATP to ADP and Pi leads to a return of the myosin cross bridge to the 90° `up' position whereupon it rebinds to actin (3). This leads to the release of the products and a return to (1). In the last step, actin is `rowed' past myosin.
