  • Proton transport by the nitrate-insensitive, vanadate-sensitive ATPase in Kl-washed microsomes and reconstituted vesicles from maize (Zea mays L.) roots was followed by changes in acridine orange absorbance in the presence of either KNO(3) or KCl. Data from such studies obeyed a kinetic model in which net proton transport by the pump is the difference between the rate of proton transport by the action of the ATPase and the leak of protons from the vesicles in the direction opposite from the… CONTINUE READING
