Erythrocytic ouabain-sensitive and ouabaininsensitive adenosine triphosphatase in various mammalian species

Abstract 1. 1. Adenosine triphosphatase activity in erythrocytes from various mammalian species is compared. 2. 2. Wide differences in values were found of both ouabain-sensitive and ouabain-insensitive adenosine triphosphatase in different species. These differences cannot be fully attributed to erythrocytic K + and Na + concentration.
