Název v původním jazyce

Lamellar organization of pigments in chlorosomes, the light harvesting complexes of green photosynthetic bacteria

Popis výsledku v původním jazyce

Chlorosomes of green photosynthetic bacteria constitute the most efficient light harvesting complexes found in nature. In addition, the chlorosome is the only known photosynthetic system where the majority of pigments (BChl) is not organized in pigment-protein complexes but instead is assembled into aggregates. Because of the unusual organization, the chlorosome structure has not been resolved and only models, in which BChl pigments were organized into large rods, were proposed on the basis of freeze-fracture electron microscopy and spectroscopic constraints. We have obtained the first high-resolution images of chlorosomes from the green sulfur bacterium Chlorobium tepidum by cryoelectron microscopy. Cryoelectron microscopy images revealed dense striations similar to20 Angstrom apart. X-ray scattering from chlorosomes exhibited a feature with the same similar to20 AAngstrom spacing. No evidence for the rod models was obtained. The observed spacing and tilt-series cryoelectron microscop
