H+/glycyl-glycine cotransport in eel intestinal brush border membrane vesicles: studies with the pH-sensitive dye acridine orange
Monitoring the fluorescence quenching of the pH-sensitive dye Acridine orange, proton accumulation in the presence of an inside-negative transmembrane potential was measured in eel (Anguilla anguilla) intestinal brush-border membrane vesicles. It was demonstrated that the proton accumulation was spe...

Summary: | Monitoring the fluorescence quenching of the pH-sensitive dye Acridine orange, proton accumulation in the presence of an inside-negative transmembrane potential was measured in eel (Anguilla anguilla) intestinal brush-border membrane vesicles. It was demonstrated that the proton accumulation was specifically increased by the presence of the dipeptide glycyl-glycine in the extravesicular space, showing saturation kinetics at increasing dipeptide concentrations and was specifically inhibited by diethylpyrocarbonate.
