Photoharvesting System II

Caption

View from above of the Photosystem II (PSII) supercomplex of light-harvesting proteins. Energy-quenching takes place in the D1 and D2 proteins (light blue and dark blue areas respectively), which are surrounded by the CP29, CP26 and CP24 proteins. Experimental results indicate that CP29, CP26 and CP24 serve as valves controlling the flow of solar energy through the energy-quencing areas.
