Since the pioneering work of Peter Mitchell 1, the central role of proton gradients in biological energy transduction has been widely ackrLowledged. The enzymes directly involved in generating and harnessing the energy of proton gradients (H+-ATPases), are found in nearly all cells and presumably appeared very early in cell evolution 2. It has been suggested that they originally functioned as a pH-stat mechanism, disposing of the excess protons generated by fermentative metabolism 3'4. The antiquity of the H+-ATPases makes them an attractive family of enzymes for evolutionary studies, particularly since functional constraints have preserved a high degree of sequence similarity across kingdoms. Indeed, analyses of eubacterial H+-ATPase sequences l'lave provided strong support for the endosymbiotic origin of mitochondria and chloroplasts 5.Recently, a new class of proton ATPases has been identified, the vacuolar ATPase (V-ATPase), which is specifically associated with the endomembrane system of eukaryotes 6-1~. Comparisons of the structure and properties of the V-ATPases with those of prokaryotic plasma membrane H+-ATPases are now providing unexpected insights into the possible origin of the eukaryotic host cell 1~(Gogarten, JP, Kibak, H., Taiz, L., Bowman, EJ, Bowman, BJ, Manolson, MF, Poole, RJ, Denda, K., Oshima, T., Konishi, J., Date, T. and Yoshida, M., submitted).
