Abstract

Kinetic parameters of enzymatic reactions and contractile responses induced by adenosine triphosphate were studied using actomyosin suspensions or glycerinated muscle fibers. The results showed excellent correlations between the enzymatic and contractile events in both muscle models. Based on comparison of the kinetic constants of the two models, it is proposed that superprecipitation and supercontraction are similar expressions of an ATP-induced contractile response in muscle models of various levels of organization.

甘油化肌纤维与肌动球蛋白悬浮液的酶学和收缩特性比较研究。
用肌动球蛋白悬浮液或甘油化肌纤维研究了三磷酸腺苷诱导的酶促反应和收缩反应的动力学参数。结果表明,在两种肌肉模型中,酶和收缩事件之间存在良好的相关性。通过对两种模型的动力学常数的比较,提出了在不同组织水平的肌肉模型中,超沉淀和超收缩是atp诱导的收缩反应的相似表达。
