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 ...
Our present understanding of the mechanism of contraction is based on fundamental discoveries, all of which arose from studies on striated muscle as the early biochemists and physiologists became ...
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 ...
Mutations in β-cardiac myosin, the predominant motor protein for human heart contraction, can alter power output and cause cardiomyopathy. However, measurements of the intrinsic force, velocity, and ...
The basic functional unit of a muscle, known as the sarcomere, consists of actin, myosin and tropomyosin proteins. If a muscle is to be able to contract, the myosin must slide along filamentous actin ...
Proceedings of the Royal Society of London. Series B, Biological Sciences Pecten 'actomyosin' as prepared by the usual dilution-precipitation procedure is reasonably pure only when obtained from the ...
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 ...
