13. Axial rotation of sliding actin filaments revealed by single-fluorophore imaging
In the actomyosin motor, myosin slides along an actin filament that has a helical structure with a pitch of ≈72 nm. Whether myosin precisely follows this helical track is an unanswered question bearing directly on the motor mechanism. Here, axial rotation of actin filaments sliding over myosin molecules fixed on a glass surface was visualized through fluor
