Method The purpose of this study was to gain information on the functional consequences of the supramolecular organization of the photosynthetic apparatus in the bacterium Rhodobacter sphaeroides. Isolated complexes of the reaction center (RC) with its core antenna ring (light-harvesting complex 1 (LH1)) were studied in their dimeric (native) form or as monomers with respect to excitation transfer and distribution of the quinone pool.
Comments There is a larger average stoichiometry (of quinones) in chromatophores (i.e. 15–25 compared with 6 in thylakoids), which entails smaller relative statistical fluctuations.
