  • Title: Onset of the sliding movement of an actin filament on myosin molecules: from isotropic to anisotropic fluctuations.
    Author: Hatori K, Honda H, Shimada K, Matsuno K.
    Journal: Biophys Chem; 1999 Nov 15; 82(1):29-33. PubMed ID: 10584294.
    Abstract:
    An actin filament contacting myosin molecules increased the fluctuation intensity of the filamental displacement as the ATP concentration increased. In particular, fluctuations in the filamental displacement in the planar plane in which the sliding movement takes place were isotropic at a low ATP concentration, and became anisotropic as the concentration increased. The build-up of the sliding movement of an actin filament was associated with the transformation from isotropic to anisotropic fluctuations of the filamental displacement.
