How myosin interacts with actin to generate force is a subject of considerable controversy. The major debate centers on understanding at what point in force generation the inorganic phosphate is released with respect to the lever arm swing, or powerstroke. Resolving the controversy is essential for...
The two cardiac myosin heavy chain isoforms, α and β, differ functionally. α Myosin exhibits higher actin-activated ATPase than does β myosin, and hear... EM Mcnally,R Kraft,M Bravo-Zehnder,... - 《Journal of Molecular Biology》 被引量: 409发表: 1989年 ...

Actin and Myosin in Muscle Contraction So, how do muscles contract? The functional units of muscle fibers are calledsarcomeres. When viewed under the microscope skeletal muscle has a striped pattern. This is because of the molecular structure of the sarcomere. Muscles are made of thousands of sa...

Algae likeCharaare also sensitive to touch. They respond to mechanical stimulation by the generation of action potentials and immediately halting cytoplasmic streaming. The increased [Ca2+]cytinhibits the interaction of actin and myosin, thus inhibiting the proteins that provide the motive force for st...
TO UNDERSTAND LIFE, you must understand proteins. These molecular chains, each assembled from a menu of 20 types of chemical links calledamino acids, do biology’s heavy lifting.In the guise ofenzymes they catalyse the chemistry that keeps bodies running.Actin and myosin, the proteins of muscles...
