Membrane vesicles isolated from Azotobacter vinelandii strain O by lysis of spheroplasts in potassium of sodium phosphate buffer develop a transmembrane electric potential during respiration. The magnitude of this potential was determined by three independent methods: (i) fluorescence of 3,3'-dipropylthiodicarbocyanine and 3,3'-dihexyloxacarbocyanine; (ii)(More)
