Covalent linkage of ethylenediamine with the Na + /K + -ATPase complex from rabbit kidney outer medulla by the use of the water-soluble carbodiimide, N -ethyl, N ′-(3-dimethylaminopropyl)carbodiimide, resulted in a 73% reaction with phosphatidylser

Several mutations of residues Glu(795) and Glu(820) present in M5 and M6 of the catalytic subunit of gastric H(+),K(+)-ATPase have resulted in a K(+)-independent, SCH 28080-sensitive ATPase activity, caused by a high spontaneous dephosphorylation rat

In this study we reveal regions of Na(+),K(+)-ATPase and H(+),K(+)-ATPase that are involved in cation selectivity. A chimeric enzyme in which transmembrane hairpin M5-M6 of H(+),K(+)-ATPase was replaced by that of Na(+),K(+)-ATPase was phosphorylated

ATP and GTP have been compared as substrates for (Na+ + K+)-ATPase in Na+-activated hydrolysis, Na+-activated phosphorylation, and the E2K----E1K transition. Without added K+ the optimal Na+-activated hydrolysis rates in imidazole-HCl (pH 7.2) are eq

(1) The transepithelial permeability for Ca2+ and Mg2+ in the isolated rabbit pancreas has been studied. (2) Values for the permeability of the unstimulated pancreas were obtained either by adding radioactive tracers to the bathing medium and measuri

(1) In view of a previously established stimulation of steady-state phosphorylation of (Na+ + K+)-ATPase by imidazole and its inhibition by tris(hydroxymethyl)aminomethane, the effect of (structure, chemical composition and charge of) a number of pri

Contrary to what has usually been assumed, (Na+ + K+)-ATPase slowly hydrolyses AdoPP[NH]P in the presence of Na+ + Mg2+ to ADP-NH2 and Pi. The activity is ouabain-sensitive and is not detected in the absence of either Mg2+ or Na2+. The specific activ
