对分离的[鸡]f -肌动蛋白细丝的图像分析表明，肌动蛋白螺旋可以用每个亚基的恒定上升来描述，但有相当大的可变和随机扭曲（每转的单位数）。肌动蛋白亚基旋转10度角的能力。从它们的螺旋理想位置有助于解释肌动蛋白形成许多不同的多形结构的能力。
Image analysis of isolated [chicken] F-actin filaments showed that the actin helix can be described by a constant rise per subunit, but a considerably variable and randomized twist (number of units per turn). The ability of actin subunits to rotate through angles of the order of 10.degree. from their helically ideal positions helps to explain actin''s capacity to form many different polymorphic structures.
