Abstract
Delipidated dogfish rectal-gland Na++K+-ATPase (Na++K+-dependent adenosine triphosphatase), almost devoid of hydrolytic activity, is able to bind about 2nmol of ADP/mg of protein. The “affinity” of delipidated enzyme for ADP is not affected by K+ in concentrations that greatly decrease the “affinity” of native Na++K+-ATPase. The K+-sensitivity of the ADP binding is in part restored by relipidation with dioleoyl phosphatidylcholine.This publication has 8 references indexed in Scilit:
