Phosphorylation of shark rectal Na,K-ATPase by ATP in the presence of Na(+) was characterized by chemical quench experiments and by stopped-flow RH421 fluorescence. The appearance of acid-stable phosphoenzyme was faster than the rate of fluorescence increase, suggesting that of the

The effect of channel-forming peptide gramicidin A on the dipole potential of phospholipid monolayers and bilayers has been studied. Surface pressure and surface potential isotherms of monolayers have been measured with a Langmuir trough equipped with a Wilhelmy balance and

To investigate Na+ binding to the ion-binding sites presented on the cytoplasmic side of the Na,K-ATPase, equilibrium Na+-titration experiments were performed using two fluorescent dyes, RH421 and FITC, to detect protein-specific actions. Fluorescence changes upon addition of Na+ in the

In the E1 state of the Na,K-ATPase all cations present in the cytoplasm compete for the ion binding sites. The mutual effects of mono-, di- and trivalent cations were investigated by experiments with the electrochromic fluorescent dye RH421. Three sites

The interaction of palytoxin with the Na,K-ATPase was studied by the electrochromic styryl dye RH421, which monitors the amount of ions in the membrane domain of the pump. The toxin affected the pump function in the state P-E2, independently of
