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.
