Computer Simulation on Kinetics of Primary Process in Photosynthesis(Ⅱ)——Energy Transfer in the β Subunits and Monomers in C-Phycocyanins

【摘要】 <正> Based on the crystal structure data of C-phycocyanins from Mastigocladus Laminosus andAgmenellum Quadruplicatum,the energy transfer processes in the βsubunits and the monomers are simulat-ed by the use of computer simulation technique.The simulation results show that excitation energy cantransfer in both directions between any pair of chromophores,and furthermore,the transfer can take place intwo opposite directions for many times between a pair of chromophores.There certainly exists energy trans-fer between the two subunits in a monomer.The dynamic nature of the energy transfer processes has beenshown.Besides,it is also indicated that a component obtained from mathematically fitting the experimentaldata cannot be equivalent to a physical process.更多还原
