Biochemical schemes for the actomyosin ATPase cycle as well as the cooperative regulation of ATPase activity are incorporated into a model of the contractile process of intact muscle. This model is shown to describe accurately the tension developed by skinned muscle fibers in the absence of Ca. This work adds to the evidence that the extrapolation of results from purified protein systems to intact muscle may be valid. Extensions to the case of Ca-activated tensions are discussed.
肌动球蛋白ATP酶循环的生化机制以及ATP酶活性的协同调节被纳入完整肌肉收缩过程的模型中。该模型被证明能够准确描述在无钙情况下皮肤化肌纤维产生的张力。这项工作进一步证明了将纯化蛋白质系统的结果外推到完整肌肉可能是有效的。文中还讨论了该模型在钙激活张力情况下的扩展。
