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 ...

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...

The standard textbook model of muscle contraction includes only two main players, the filaments actin and myosin, which slide past each other, causing the sarcomere—the basic unit of muscle tissue—to ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 95, No. 6 (Mar. 17, 1998), pp. 2944-2949 (6 pages) For more than 30 years, the fundamental goal in molecular ...

A 35-70% ammonium sulfate fraction of smooth muscle actomyosin was prepared from guinea pig vas deferens. This fraction also contains a smooth muscle myosin kinase and a phosphatase that ...

At the molecular level, muscle contraction is defined by myosin molecules pulling actin filaments. New electron cryomicroscopy images with unprecedented resolution taken by researchers at Osaka ...
