Band Structure of the Rhodobacter sphaeroides Photosynthetic Reaction Center from Low-Temperature Absorption and Hole-Burned Spectra

Autor: Mahboobe Jassas, Adam Kell, Ryszard Jankowiak, Olga Rancova, Darius Abramavicius

Publikováno v: The Journal of Physical Chemistry B. 120:5601-5616

Persistent/transient spectral hole burning (HB) and computer simulations are used to provide new insight into the excitonic structure and excitation energy transfer of the widely studied bacterial reaction center (bRC) of Rhodobacter (Rb.) sphaeroide

We provide an analysis of the pigment composition of reconstituted wild type CP29 complexes. The obtained stoichiometry of 9 +/- 0.6 Chls a and 3 +/- 0.6 Chls b per complex, with some possible heterogeneity in the carotenoid binding, is in agreement

The B800-850 LH2 antenna from the photosynthetic purple sulfur bacterium Allochromatium vinosum exhibits an unusual spectral splitting of the B800 absorption band; i.e., two bands are well-resolved at 5 K with maxima at 805 nm (B800R) and 792 nm (B80

Publikováno v: The journal of physical chemistry. B. 121(17)

Identification of the lowest energy pigments in the photosynthetic CP47 antenna protein complex of Photosystem II (PSII) is essential for understanding its excitonic structure, as well as excitation energy pathways in the PSII core complex. Unfortuna
