The relationship between the actin-activated adenosinetriphosphatase activity of smooth muscle myosin and the extent of myosin light chain phosphorylation is nonlinear. It is suggested that the phosphorylation of the two heads of smooth muscle myosin is an ordered process and that the two heads are influenced by cooperative interactions.
平滑肌肌球蛋白的肌动蛋白激活的三磷酸腺苷酶活性与肌球蛋白轻链磷酸化程度之间的关系是非线性的。有人提出,平滑肌肌球蛋白两个头部的磷酸化是一个有序过程,且这两个头部受协同相互作用的影响。
