Mechanisms for photosystems I and II.
Using structural information from recently published crystal structures of photosystems I and II, the processes of excitation energy transfer and electron transfer in oxygenic photosynthesis have been studied in great detail by experimental and theoretical methods. Although both systems share numerous common structural and functional features, efficiency and regulation are differently weighted in the individual processes that are involved in the transformation of light energy into chemical energy in the two complexes.
