Photosynthesis is the biological process by which light energy is captured and converted into biochemical energy, and it is the primary energy source for the majority of life on Earth. Photosynthetic organisms, including plants, algae and specialised bacteria, contain light-harvesting pigment-protein complexes, which absorb solar energy.
The first stages of photosynthesis involve harvesting solar energy by light-harvesting (LH) antenna complexes, then transfer to a specialized, membrane-bound complex called the reaction centre (RC) where this energy is trapped as a charge separation. However, Photosynthesis uses a limited range of the solar spectrum, so enhancing spectral coverage could improve the efficiency of light capture. Here, we show that a hybrid reaction centre (RC)/yellow fluorescent protein (YFP) complex, which creates new energy transfer pathways that augment energy transfer and trapping in photosynthesis. Thus, photosynthetic growth has been accelerated in the bacterium Rhodobacter sphaeroides.
