[Regulation of the number of k-binding sites of Na,K-ATPase by adenosine triphosphate].
A possible existence of two functional states of Na,K-ATPase with different electrogenic coefficients has been experimentally proved. Regulation of electrogenicity is achieved by alteration in the number of K+ transport sites. A transition of Na,K-ATPase from one functional state to the other has been shown to occur during the binding of ATP free ions.
