COMPUTER-SIMULATION ON KINETICS OF PRIMARY PROCESS IN PHOTOSYNTHESIS .2. ENERGY-TRANSFER IN THE BETA-SUBUNITS AND MONOMERS IN C-PHYCOCYANINS

Based on the crystal structure data of C-phycocyanins from Mastigoclad us. Laminosus and Agmenellum Quadruplicatum, the energy transfer proce sses in the beta subunits and the monomers are simulated by the use of computer simulation technique. The simulation results show that excit ation energy can transfer in both directions between any pair of chrom ophores, and furthermore, the transfer can take place in two opposite directions for many times between a pair of chromophores. There certai nly exists energy transfer between the two subunits in a monomer. The dynamic nature of the energy transfer processes has been shown. Beside s, it is also indicated that a component obtained from mathematically fitting the experimental data cannot be equivalent to a physical proce ss.
