(A Center for the Study of Early Events in Photosynthesis)
The first 2 1/2 years of the Center have been very productive. Research completed by Center scientists has resulted in publication or acceptance of 60 papers, with several more currently under consideration. Individual project summaries are as follows: J. P. Allen is investigation molecular mechanisms of the reaction center, and influence of protein structure on the electronic properties of the primary electron donor. R. E. Blankenship is investigating the structure and function of chlorosome antennas in green photosynthetic bacteria. D. Brume is investigating the organization of chlorosomes and characterizing the role of proteins in chlorosomes. W. D. Frasch is studying the structure and mechanism of the two manganese requiring photosynthetic enzymes, the oxygen evolving complex and the energy transducing complex. D. Gust, T. A. Moore and A. L. Moore are investigating artificial photosynthesis systems where proteins have been replaced by covalent linkages between pigments molecules. S. H. Lin is developing a theory to explain photoinduced electron transfer and femto-second processes. G. R. Seely has developed a self-assembling model of primary charge separation in photosynthesis. W. F. J. Vermaas is optimizing site-directed mutagenesis studies of the acceptor side of photosystem 2. A. N. Webber is studying the biogenesis of photosystem 1 and 2 reaction center complexes in plants, green algae, and cyanobacteria. N. W. Woodbury is studying chimeric reaction centers and a reaction center symmetry mutant. 60 refs. (MHB)
