Photophosphorylation in photosynthetic membranes of plants (thylakoid membranes) is driven by an electrochemical potential difference of the proton1. The light-driven net uptake of protons into the thylakoid lumen is electrically balanced by the motion of other ions2,3. So far no ion channel has been identified in thylakoids other than the proton channel of the ATP synthase4 although charge balance would call for one. Patch-clamp studies5 on isolated membrane patches from osmotically inflated… CONTINUE READING
