Then, the myosin heads bind to actin and cause the actin filaments to slide. Finally, ATP breaks the actin-myosin bond and allows another myosin 'oar stroke' to occur. Repetition of these events

Muscle contraction consists of a cyclical interaction between myosin and actin driven by the concomitant hydrolysis of adenosine triphosphate (ATP). A model for the rigor complex of F actin and the myosin head was obtained by combining the molecular structures of the Muscle contraction consists of a cyclical interaction between myosin and actin driven by the concomitant hydrolysis of adenosine triphosphate (ATP). A model for the rigor complex of F actin and the The structure of the complex between actin and myosin subfragment 1 (S1), designated the acto-S1 complex, in the presence of ATP was examined by electron microscopy. This was accomplished by using negative staining to study a complex of S1 covalently crosslinked to actin by the zero-length crosslinker, 1-ethyl-3-[3-(dimethylamino)-propyl]carbodiimide.

Ca++ then binds to troponin C in the troponin complex, which ultimately causes a shift in position of tropomyosin molecules on the actin filament. This exposes sites on actin monomers in the filament that can be bound by the molecular motor, myosin, the major protein of the thick filaments within the sarcomere. See Figure 1 and Figure 2.
