This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop on "Antennas and Reaction Centers of Photosynthetic Bac teria" was held at Feldafing, Bavaria (F. R. G. )' March 23-25, 1985. This workshop focussed on primary processes with emphasis on structure, inter actions and dynamics. It assessed structural, spectroscopic and dynamic data which have accumulated recently, providing an overview of the mech anism of the acquisition, storage and useful disposal of energy in bacterial photosynthesis. This volume is a record of the invited papers presented at the workshop. The material was organized into five sections: I. Antennas: Structure and Energy Transfer II. Reaction Centers: Structure and Interactions III. Electron Transfer: Theory and Model Systems IV. Reaction Cen,ters: Structure and Dynamics V. Model Systems on Function of Antennas and Reaction Centers I would like to express my gratitude to all the participants in the work shop for their contributions, and to the authors for the timely preparation of their manuscripts. I am indebted to the members of the organizing committee, Professors Sighart F. Fischer and Hugo Scheer for their most valuable assistance and advice. The workshop would not have been so successful without the help of my secretary, Frau Petra KahlfuB, and my coworkers in its organization. I thank Frau KahlfuB particularly also for her assistance in the preparation of these proceedings. The workshop was organized under the auspices of the Technical Uni versity of Munich, the Max-Planck-Society and the University of Munich.

Book Synopsis Photosynthetic Reaction Center by : Johann Deisenhofer
Download or read book Photosynthetic Reaction Center written by Johann Deisenhofer and published by Academic Press. This book was released on 2013-10-22 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability of the photosynthetic reaction center's structure at an atomic resolution of less than three angstroms has revolutionized research. This protein is the first integral membrane protein whose structure has been determined with such precision. Each volume of the Photosynthetic Reaction Center contains original research, methods, and reviews. Together, these volumes cover our current understanding of how photosynthesis converts light energy into stored chemical energy. Volume II details the electron transfer process; it is oriented to the physical aspects of photosynthesis. It thus primarily discusses bacterial photosynthesis and model compounds. Volume II features the very complex and rapidly evolving issues associated with the theory of electron transfer in the bacterial reaction center, and explores picosecond and femtosecond spectroscopy. This volume also covers holeburning spectroscopy; primary events of bacterial photosynthesis with emphasis on the application of large, external electric fields designed to manipulate and probe mechanisms of the initial chemistry; the role of accessory carotenoid pigments; the techniques of infrared spectroscopy and magnetic resonance as applied to photosynthesis; and the interplay between natural and artificial photosynthesis.

This book was released on 2013-06-29 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the contributions from the speakers at the NATO Advanced Research Workshop on "Structure of the Photosynthetic Bacterial Reaction Center X-ray Crystallography and Optical Spectroscopy with Polarized Light" which was held at the "Maison d'Hotes" of the Centre d'Etudes Nucleaires de Cadarache in the South of France, 20-25 September, 1987. This meeting continued in the spirit of a previous workshop which took place in Feldafing (FRG), March 1985. Photosynthetic reaction centers are intrinsic membrane proteins which, by performing a photoinduced transmembrane charge separation, are responsible for the conversion and storage of solar energy. Since the pioneering work of Reed and Clayton (1968) on the isolation of the reaction center from photosynthetic bacteria, optical spectroscopy with polarized light has been one of the main tools used to investigate the geometrical arrangement of the various chromophores in these systems. The recent elucidation by X-ray crystallography of the structure of several bacterial reaction centers, a breakthrough initiated by Michel and Deisenhofer, has provided us with the atomic coordinates of the pigments and some details about their interactions with neighboring aminoacid residues. This essential step has given a large impetus both to experimentalists and to theoreticians who are now attempting to relate the X-ray structural model to the optical properties of the reaction center and ultimately to its primary biological function.

This book was released on 2012-12-06 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reaction Centers of Photosynthetic Bacteria is an updated record on the most recent insight into the struc- ture/function relationship of reaction centers from photosynthetic bacteria. It addresses in particular, interactions and dynamics which determine the ultra-high quantum yield of photoinduced charge separation in these energy-transforming molecular machines. Of particular interest is the still controversial issue of the primary charge separation mechanism as well as the effects of well-defined modifications, introduced either by mutagenic replacements in the protein matrix or by chemical exchange of reaction center pigments. Also described are the methods used for the characterization of interactions and dynamics important for electron transfer processes in the reaction center.

Book Synopsis The Photosynthetic Bacterial Reaction Center II by : Jacques Breton
Download or read book The Photosynthetic Bacterial Reaction Center II written by Jacques Breton and published by Springer. This book was released on 1992 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Research Workshop entitled "The Photosynthetic Bacterial Reaction Center: Structure, Spectroscopy, and Dynamics" was held May 10-15, 1992, in the Maison d'H6tes of the Centre d'Etudes Nuc1eaires de Cadarache near Aix-en-Provence in the south of France. This workshop is the most recent of a string of meetings which started in Feldafing (Germany) in March 1985, soon after the three-dimensional structure of the bacterial reaction center had been elucidated by X-ray crystallography. This was followed, in September 1987, by a workshop in Cadarache and, in March 1990, by a second meeting in Feldafing. Although one of the most important processes on Earth, photosynthesis is still poorly understood. Stimulated by the breakthrough of solving the bacterial reaction center structure at atomic resolution, the field of relating this structure to the function of the reaction center, i. e. the remarkably efficient conversion and storage of solar energy, has been developing vigorously. Once the general organization of the cofactors and some details of the protein-cofactor interactions were known, it became possible to combine a variety of spectroscopic techniques with the powerful tool of site-directed mutagenesis in order to address increasingly incisive questions about the specific role of some amino acid residues in the electron transfer process. Still another promising tool is being developed, namely the exchange of a number of the native bacteriochlorophyll and bacteriopheophytin cofactors by chemically modified pigments.
Book Synopsis Energy and Electron Transfer in Photosynthetic Reaction Centers and Biohybrid Antenna Complexes by : Michelle Alice Harris
Download or read book Energy and Electron Transfer in Photosynthetic Reaction Centers and Biohybrid Antenna Complexes written by Michelle Alice Harris and published by . This book was released on 2014 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on two areas studied in an effort to increase important fundamental understandings of electron and energy transfer events leading to solar conversion in natural and artificial systems: (1) electron transfer in the bacterial photosynthetic reaction center (RC) and (2) biohybrid photosynthetic light harvesting (LH) complexes containing native-like peptides and synthetic chromophores. The RC in photosynthetic bacteria converts light energy to chemical energy through a series of electron transfer steps to separate charge across a membrane. The native process has a ~100% quantum yield of electron transfer down one cofactor branch (the L-side) whereas the seemingly symmetrical branch (the M-side) with identical pigments is inactive. Understanding M-side inactivity has been the goal of numerous studies, and has been investigated through mutations of the native peptides to favor electron transfer down the M-side or disfavor electron transfer down the L-side. In these mutants, the normal bacteriochlorophyll-bacteriochlorophyll primary electron donor is replaced with a bacteriochlorophyll-bacteriopheophytin dimer (bacteriopheophytin is the Mg-free analog of bacteriochlorophyll). This switch alters the mechanisms, rates, and yields of electron transfer in heterodimer RCs compared to wild-type. We have investigated the effects of three further mutations in which either the L or M macrocycle of the dimer is a bacteriopheophytin, for a total of eight combinations (e.g., addition of a hydrogen bond to the dimer, swap of nearby amino acids). Using ultrafast transient absorption spectroscopy to observe changes in the rate and the yield of L- versus M-side charge separation, the contributions of the electronic and energetic factors to directionality of electron transfer in RCs were assessed. The second area of my studies has been to investigate biohybrid antenna complexes formed by combining native-length bacterial LH peptide analogs with designer chromophores. The native LH systems are highly efficient. When a photon is absorbed, the energy is transferred to the RC with near unity quantum yield. However, the complex doesn't absorb parts of the solar spectrum in the visible and near-infrared regions. To address this deficiency, we performed four major studies on biohybrid antennas: (1) relay energy transfer between, (2) studies on location, density and spectral coverage of conjugated chromophores, (3) studies on bioconjugatable chromophores of hydrophobic, hydrophilic and amphiphilic nature, and (4) incorporation of non-bioconjugatable amphiphilic chromophores. Static emission and transient absorption studies indicate energy transfer efficiencies comparable to those found in native antenna systems.
