The capacity of thallium to substitute for K + in activation of (Na + , K + )‐ATPase of liver plasma membranes was studied. Our results indicate that Tl + can replace K + in the activation of the (Na + , K + )‐ATPase of liver plasma membranes. In the presence of Na + , similar activation is obtained with Tl + concentrations only 1/10 of those of K + . In all other aspects, the (Na + , K + )‐ and (Na + , Tl + )‐ATPases were found to be identical.
