Papain digestion of the subunits of (Na,K)-ATPase.
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.
