Excitation Energy Transfer in Photosynthetic Systems: Pigment Oligomerization Effect

Part of the FEMS Symposium book series (FEMSS)


Our previous theoretical analysis has shown that the structure of a photosynthetic unit (PSU) should be strictly optimized in vivo to ensure the high quantum yield values (~90%) found experimentally for the primary photochemistry (Fetisova and Fok, 1984). We have already studied the basic principles of the Structural organization of an optimal model light-converting systems with certain simple types of their lattices (Fetisova, Fok and Shibaeva, 1985; Fetisova and Shibaeva, 1987). However, in all the known photosynthetic organisms, the three-dimensional array of pigment-protein complexes form the cluster structure of the PSU lóttice: the distances between molecules within a single complex are ~ 10 Å, while for the nearest neighbour molecules which belong to adjacent complexes the distances are 20 – 30 Å.
