Artificial antenna systems and reaction centres synthesized in our laboratory are used to illustrate that structural and thermodynamic factors controlling energy and electron transfer in these constructs can be modified to optimize performance. Artificial reaction centres have been incorporated into liposomal membranes where they convert light energy to vectorial redox potential. This redox potential drives a Mitchellian, quinone-based, proton-transporting redox loop that generates a δμH+ of ca. 4.4 kcal mol-1 comprising δpH ca. 2.1 and δΨ ca. 70 mV. In liposomes containing CF0F1-ATP synthase, this system drives ATP synthesis against an ATP chemical potential similar to that observed in natural systems.
