In searching for an enzymatic basis for sodium transport Skou ('57) discovered in particles from crab nerve a unique Mg++-activated adenosine triphosphatase (ATPase) activity which required both sodium and potassium ions together. Subsequently Post et al.('60) identified a similar ATPase activity in broken erythrocyte membranes as part of the system for the active transport of sodium and potassium intact red cells. The identification was made on the basis of nine corresponding characteristics. Inhibition by the cardiac glycoside, ouabain, was one of these. Identification by different criteria was made by Dunham and Glynn ('61), Hoffman ('62), and Tosteson et al.('60). Bonting et al.('62) found a qualitative correlation between ouabain-sensitive ATPase activity and ouabain-sensitive sodium and potassium transport in eight different tissues. The activity has been found in nerve cell membranes (Bonting and Caravaggio,'62; Cummins and Hydkn,'62) liver cell membranes (Emmelot and Bos,'62), in intestine (Taylor,'62), and in heart muscle (Skou,'62; Auditore,'62; Yu and Lee,'62; Schwartz,'62). Detailed studies of brain preparations have been made by Jarnefelt ('62), Deul and McIlwain ('61), Skou ('62), Somogyi and Vincze ('62), Aldridge ('62), Yoshida and Fujisawa ('62), and Schwartz, Bachelard, and McIlwain ('62). In kidney Whittam and Wheeler ('62) and Landon ('62) have demonstrated a similar activity and Skou has characterized a particularly active preparation ('62). The present paper describes the properties of an equally active but different preparation. The properties correspond so closely with those of the (Na++ K+) transport ATPase activity in human erythrocyte membranes as to suggest that the basis mechanism of active sodium and potassium transport is the same in the two tissues. Preliminary reports of this work have appeared (Kinsolving and Post,'60; Post,'61).
