    The interaction between the light-harvesting antenna (LH1) and the reaction center (RC) in the photosynthetic purple bacteria Rhodobacter sphaeroides R26 and strain was studied with low-temperature ( K) absorbance-detected magnetic resonance (ADMR) experiments combined with computer simulations. The triplet-minus-singlet (T−S) spectra of chromatophores of Rb. sphaeroides Cited by: The light-harvesting core antenna (LH1) and the reaction centre (RC) of purple photosynthetic bacteria form a supramolecular complex (LH1-RC) to use sunlight energy in a highly efficient manner.

    Anoxygenic Photosynthetic Bacteria is a comprehensive volume describing all aspects of non-oxygen-evolving photosynthetic bacteria. The 62 chapters are organized into themes of: Taxonomy, physiology and ecology; Molecular structure of pigments and cofactors; Membrane and cell wall structure: Antenna structure and function; Reaction center structure and electron/proton pathways; Cyclic electron Reviews: 1. cyanobacteria, and anoxygenic photosynthetic bacteria to convert energy harvested from light into a chemical form.1,2 It is initiated by a sequence of remarkable and finely tuned photophysical and photochemical reactions (see Scheme 1, top). The process of photosynthesis, which takes place over aFile Size: 1MB.

    Publisher Summary. This chapter discusses electron transfer mechanisms in reaction centers. Biological electron transfer has been made possible by the solution of the X-ray diffraction structure of two photosynthetic reaction centers and by extensive measurements on the free-energy dependence of photosynthetic electron transfer reactions. Photosynthesis Part 1. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A reaction center b) An antenna complex c) A chlorophyll pair d) A carotenoid antenna The reaction center of purple photosynthetic bacteria contains a ____ bacteriochlorophyll a molecule(s).

This protein is the first integral membrane protein whose structure has been determined with such precision.

In photosynthesis, light energy conversion proceeds in two steps [1]. First excitons are generated in antenna systems and subsequently charge separation takes place in reaction centers (RCs. The initial approaches to mimicking reaction centers for AP in the late s consisted of linking two molecular analogs of components involved in the natural photosynthetic reaction center with covalent bonds (e.g., porphyrins, carotenoids, chlorophylls, pheophytins, phthalocyanines and quinones).

In this context, quinones are compounds Cited by: Excitons are considered as the basic concept used by describing the spectral properties of photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light-harvesting.
