Microsomal vesicles prepared from the ER and the Golgi apparatus of maize coleoptiles possess an ATP-fueled, Cl - -dependent proton pump which can cause an intravesicular acidifica­tion of the vesicles (A. Hager and M. Helmle, Z. Naturforsch. 36 c, 997 (1981); A. Hager et al., Z. Naturforsch. 35 c, 783-793 (1980)). This acidification is very specifically inhibited by Ca 2+ . The inhibition is already distinct at concentrations of 30 μᴍ. While 10-fold higher concentrations of La 3+  produce similar effects, Mg 2+  remains ineffective even at very high concentrations.
