The Na+/ K+-ATPase restores sodium (Na+) and potassium (K+) electrochemical gradients dissipated by action potentials and ion-coupled transport processes. As ions are transported, they become transiently trapped between ...

Marked differences in the activities of three monovalent cation transport systems in horse versus human erythrocytes are reported. Whereas horse erythrocytes exhibit a 6-fold higher sodium-lithium countertransport, the ...

The properties of the Na/K pump and Na, K, Cl cotransporter were studied in vascular tissue of two-kidney Goldblatt hypertensive rats. These transport systems were measured as ouabain-sensitive and bumetanide-sensitive ...

Several partial reactions of the Na+-K+ pump enzyme were studied in a microsomal fraction derived from the gill of carp (Cyprinus carpio Linneo). We tested the effect of three toxins [(i) microcystin-LR (ii) microcystin-LR-like ...

The Na +/K + pump is a nearly ubiquitous membrane protein in animal cells that uses the free energy of ATP hydrolysis to alternatively export 3Na + from the cell and import 2K + per cycle. This exchange of ions produces a ...
