The Proton Pumps of the Plasmalemma and the Tonoplast of Higher Plants
The Proton Pumps of the Plasmalemma and the Tonoplast of Higher Plants
- Journal of Bioenergetics and Biomembranes, 17(1), p.1-21, 1985 .
Studies on intact cells, membrane vesicles, and reconstituted proteoliposomes have demonstrated in higher plants the existence of an ATP-driven electrogenic proton pump operating at the plasmalemma. There is also evidence of a second ATP-driven H + pump localized at the tonoplast. The characteristics of both these ATP-driven pumps closely correspond to those of the plasmalemma and tonoplast proton pumps of Neurospora and yeasts.
