Sealed microsomal membrane vesicles were prepared from leaves of a 250 millimolar NaCl-grown halophyte (Atriplex gmelini C. A. Mey). The vesicles exhibited ATP-dependent proton-transporting activity which was inhibited 60% by NO(3) (-) (50 millimolar) but not by vanadate (100 micromolar) and 23% by oligomycin (10 micrograms per milliliter), suggesting that tonoplast-derived vesicles were the ma...
