The paper deals with some data on nonidentical heat-resistance of actomyosin of the skeletal muscles and myocardium of the calf foetus and adult animals. It is shown that in the process of uterine development the ATPase activity increases and at alkaline pH the Ca2+-activated ATPase of natural actomyosin of the cattle skeletal muscles and myocardium is activated. Heat-resistance of ATPase of the skeletal muscles and myocardium decreases with age, the myocardium actimyosin ATPase being more stable to heating. These denatured changes are found to be of a reversible character.
本文研究了小牛胎儿和成年动物骨骼肌与心肌中肌动球蛋白不同耐热性的一些数据。结果表明，在子宫发育过程中，ATP酶活性增加，在碱性pH值下，牛骨骼肌和心肌天然肌动球蛋白的Ca2+激活ATP酶被激活。骨骼肌和心肌ATP酶的耐热性随年龄增长而降低，心肌肌动球蛋白ATP酶对加热更稳定。这些变性变化具有可逆性。
