2019-02-26 · Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction.
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 individual proteins with the low-resolution electron density maps of the complex derived by cryo-electron microscopy and image

See Figure 1 and Figure 2. the actin-tropomyosin-myosin complex in the rigor (nucleotide-free) state determined by cryo-EM. The pseudoatomic model of the complex, obtained from fitting crystal structures into the map, defines a large actin-myosin-tropomyosin interface. This interface involves two adjacent actin monomers and one tropo- Attempts to crystallize the complex have been unsuccessful. However, incubating myosin heads (subfragment 1, S1) with filamentous actin (f-actin) produces “decorated actin” in which each myosin head binds to the actin filament in the strong-binding or “rigor” configuration. As myosin and actin interact in the presence of ATP, they form a tight compact gel mass; the process is called superprecipitation. Actin-myosin interaction can also be studied in Muscle - Muscle - Actin-myosin interaction and its regulation: Mixtures of myosin and actin in test tubes are used to study the relationship between the ATP breakdown reaction and the interaction of myosin and actin.
