K. Hatori et al., STAGGERED MOVEMENT OF AN ACTIN FILAMENT SLIDING ON MYOSIN MOLECULES IN THE PRESENCE OF ATP, Biophysical chemistry, 70(3), 1998, pp. 241-245
An actin filament sliding on myosin molecules in the presence of an ex
tremely low concentration of ATP exhibited a staggered movement. Longi
tudinally 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 fi
lament indicate establishment of a coordination of ATP-mediated active
sites distributed along the filament. (C) 1998 Elsevier Science B.V.
