Structural organization and energy storage in crosslinked actin assemblies
Fig 6
Schematic illustration of a possible mechanism for torque generation by sequential detachment of crosslinkers.
(A) Two filaments in parallel are crosslinked on every other subunit. From left to right, crosslinkers are detached from the pointed end (−) to the barbed end (+) sequentially. Upon detachment of a crosslinker (yellow symbols), both filaments rotate around their axes counterclockwise. (B) The angular displacement of the filament upon every detachment is π/13.
