Abstract

An actin filament sliding on myosin molecules in the presence of an extremely low concentration of ATP exhibited a staggered movement. Longitudinally sliding movement of the filament was frequently interrupted by its non-sliding, fluctuating movements both in the longitudinal and transversal directions. Intermittent sliding movements of an actin filament indicate establishment of a coordination of ATP-mediated active sites distributed along the filament.

摘要

在极低浓度的三磷酸腺苷（ATP）存在的情况下，肌动蛋白丝在肌球蛋白分子上滑动时呈现出交错运动。肌动蛋白丝的纵向滑动运动经常被其在纵向和横向的非滑动、波动运动打断。肌动蛋白丝的间歇性滑动运动表明沿着肌动蛋白丝分布的三磷酸腺苷介导的活性位点建立了协调。
