  1. Comparison between the Light-Harvesting Mechanisms of Type-I Photosynthetic Reaction Centers of Heliobacteria and Photosystem I: Pigment Site Energy Distribution and Exciton State Reviewed International journal

    The photosynthetic pigment system on the anoxygenic type-I reaction center of heliobacteria (hRC), which has a symmetrical structure, was analyzed. The excitonic coupling among all of the bacteriochlorophyll g (BChl-g) molecules and chlorophyll a (Chl-a) molecules and the site energy for each pigment were calculated using Poisson-TrESP and the charge density coupling (CDC) methods. The obtained theoretical model reproduced the optical absorption and circular dichroism spectra. It also interpreted the decay-associated spectra upon the photoselective laser excitation, which represent the ultrafast excitation energy migration process, better than the simpler hRC models that assumed constant pigment site energy shifts. Spatial movements of excitation energy on pigments on hRC upon the laser excitation were visualized. The energy dissipation by carotenoid molecules in hRC was also predicted. The hRC model was compared with the model of the reaction center of cyanobacterial photosystem I (PSI), which carries 95 Chl-a on the analogous type-I structure with significantly different amino-acid sequences, pigment species, and output redox powers. It is shown that the locations and site energy values of pigments in hRC resemble those in the core of PSI, except for the red-Chl-a sites, suggesting common functional mechanisms implicated in their evolution.

    General theory of the excitation energy transfer EET in the case of donor-mediator-acceptor
    system was constructed by using generalized master equation GME. In this theory, we consider the
    direct and indirect transitions in the EET consistently. Hence, our theory includes the quantum
    mechanical interference between the direct and indirect transitions automatically. Memory functions
    in the GME were expressed by the overlap integrals among the time-dependent emission spectrum
    of the donor, the absorption spectrum of the mediator, the time-dependent emission spectrum of the
    mediator, and the absorption spectrum of the acceptor. In the Markov limit of the memory functions,
    we obtained the rate of EET which consists of three terms due to the direct transition, the indirect
    transition, and the interference between them. We found that the interference works effectively in
    the limit of slow thermalization at the intermediate state. The formula of EET rate in this limit was
    expressed by the convolution of the EET interaction and optical spectra. The interference effect
    strongly depends on the width of the absorption spectrum of mediator molecule and the energy gap
    between the donor and the mediator molecules.

  10. *Advanced Theory of Excitation Energy Transfer in Dimers Reviewed

    Authorship:Lead author   Language:English   Publishing type:Research paper (scientific journal)  

    Previously, we developed a unified theory of the excitation energy transfer (EET) in dimers, which is applicable
    to all of the cases of excitonic coupling strength (Kimura, A.; Kakitani, T.; Yamato, T. J. Phys. Chem. B
    2000, 104, 9276). This theory was formulated only for the forward reaction of the EET. In the present paper,
    we advanced this theory so that it might include the backward reaction of the EET as well as the forward
    reaction. This new theory is formulated on the basis of the generalized master equation (GME), without
    using physically unclear assumptions. Comparing the present result with the previous one, we find that the
    excitonic coupling strengths of criteria between exciton and partial exciton and between hot transfer and
    hopping (Fo¨rster) mechanisms are reduced by a factor of 2. The critical coherency èc is also reduced
    significantly.
