Myosin V Is a Left-Handed Spiral Motor on the Right-Handed Actin Double Helix                               400mM ATP 4x fast replay 2 revolutions in ~4.4 mm.     40mM ATP 4x fast replay 1 revolutions in ~2 mm. Movies: Upper panel, transmitted images showing the bead movement; lower panel, fluorescence image showing the fluorescently labelled actin filament.  The bead appears white when it is closer to, and black when farther from, the observer. Dot on a bead (every 10 frames) indicates the bead carrying myosin V.       10mM ATP 16x fast replay 1.5 revolutions in ~3 mm. M. Y. Ali et al., Nature Struct. Biol. 9, 464-467 (2002).
