Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

Myosin converts this energy by hydrolyzing ATP molecules into movement along an actin filament. The hydrolysis involves a number of conformational changes in myosin.

ATP is critical for the contraction of muscles; it binds to myosin to provide energy and facilitate its binding to actin to form a cross-bridge. ADP and phosphate are then released and a new ATP ...

Myosin in muscles behaves in a unique way, which might explain why muscles have such strong contractile power. A cartoon showing the asymmetry in the weak binding between myosin and actin that biases ...

Muscle contraction is driven by cyclic association and dissociation of myosin head of the thick filament with thin actin filament coupled with ATP binding and hydrolysis by myosin. However ...

Over the last several years the identification and functional characterization of the motor proteins actin and myosin in the nucleus has initiated a change in the view of nuclear processes. It is now ...

The actin and myosin complex (actomyosin) generates contraction force of a muscle utilizing the adenosine triphosphate (ATP) hydrolysis reaction. Many attempts have thus been made to explain the ...
