Artificial photosynthesis in ranaspumin-2 based foam.
We present a cell-free artificial photosynthesis platform that couples the requisite enzymes of the Calvin cycle with a nanoscale photophosphorylation system engineered into a foam architecture using the Tungara frog surfactant protein Ranaspumin-2. This unique protein surfactant allowed lipid vesicles and coupled enzyme activity to be concentrated to the microscale Plateau channels of the foam, directing photoderived chemical energy to the singular purpose of carbon fixation and sugar synthesis, with chemical conversion efficiencies approaching 96%.
