Membrane-bound (Na,K)-ATPases were exposed to limited papain digestion. We could not find the active (Na,K)-ATPase lacking glycoprotein subunit for the enzymes from three different sources (outer medulla of dog kidney, electric organs of Narke japonica and larvae of Artemia salina). It seemed unlikely that the glycoprotein subunit was selectively removed from (Na,K)-ATPase by papain digestion.
将膜结合的(钠,钾)-ATP酶暴露于有限的木瓜蛋白酶消化中。对于来自三种不同来源(犬肾外髓质、日本电鳐的电器官和卤虫幼虫)的酶,我们未能找到缺乏糖蛋白亚基的活性(钠,钾)-ATP酶。木瓜蛋白酶消化似乎不太可能从(钠,钾)-ATP酶中选择性地去除糖蛋白亚基。
