Abstract
Troponin in bullfrog skeletal myofibrils was substituted by troponin T and troponin T1 from rabbit skeletal muscle. The inhibitory effect of troponin I was examined on the ATPase activity of these troponin-substituted myofibrillar preparations. The ATPase of myofibrils substituted by troponin T was more inhibited by troponin I than the ATPase of myofibrils substituted by troponin T1.
摘要
牛蛙骨骼肌肌原纤维中的肌钙蛋白被兔骨骼肌的肌钙蛋白T和肌钙蛋白T1所取代。研究了肌钙蛋白I对这些肌钙蛋白取代的肌原纤维制剂ATP酶活性的抑制作用。与被肌钙蛋白T1取代的肌原纤维的ATP酶相比，被肌钙蛋白T取代的肌原纤维的ATP酶受肌钙蛋白I的抑制作用更强。
