Abstract
The maximum sliding velocity of rabbit skeletal-muscle myosin is about 10 mu m/sec under zero load and physiological conditions. We have fou nd, however, that a large glass-bead (diameter, 65 mu m) coated by rab bit skeletal myosin slides at 338 +/- 47 mu m/sec under a condition su spended from an actin paracrystal surface. Also the sliding velocity i ncreases exponentially as the size of myosin-coated glass-beads increa ses. We report here that the sliding velocity of myosin can be control led by the adhesion force and the external normal force acting between actin and myosin. (C) 1997 Academic Press.
