Abstract Photophosphorylation in halobacteria is carried out by two rather simple elements: an A-type ATP synthase and light-driven ion-pumping bacterial rhodopsins. The unique features of halobacterial ATP synthase, mostly common to archaebacteria (A-type), and of new members of the bacteriorhodopsin family are introduced along with studies performed in the authors' laboratory. This is the story of how we found that the A-type ATP synthase is close to V-type ATPase but far from F-type ATPase, although all three ATPases are believed to have the same ancestor. Archaerhodopsins, the new members of the proton-pumping retinal proteins, were found in Australian halobacteria and have been used in a comparative study of bacterial rhodopsins.
