Asymmetric structure of the native Rhodobacter sphaeroides dimeric LH1–RC complex
Nature Communications, 2022 Rhodobacter sphaeroides is a model organism for studying bacterial photosynthesis. Here, the authors present structures of its native dimeric and a protein-U-lacking monomeric light-harvesting-reaction center complexes, which reveal asymmetric features ...

Fluorescence blinking of single major light-harvesting complexes
New Journal of Physics, 2013 Recent time-resolved studies have revealed the switching behavior of single photosynthetic light-harvesting complexes. In this work, we suggest a conceptual diffusion-controlled model, which is able to describe essential protein dynamics underlying this ...

From isolated light-harvesting complexes to the thylakoid membrane: a single-molecule perspective
Nanophotonics, 2018 The conversion of solar radiation to chemical energy in plants and green algae takes place in the thylakoid membrane. This amphiphilic environment hosts a complex arrangement of light-harvesting pigment-protein complexes that absorb light and transfer ...

Bio-inspired building blocks for all-organic metamaterials from visible to near-infrared
Nanophotonics, 2023 Light-harvesting complexes in natural photosynthetic systems, such as those in purple bacteria, consist of photo-reactive chromophores embedded in densely packed “antenna” systems organized in well-defined nanostructures.

Carotenoid-dependent singlet oxygen photogeneration in light-harvesting complex 2 of Ectothiorhodospira haloalkaliphila leads to the formation of organic hydroperoxides and damage to both pigments and protein matrix [PDF]
PeerJEarlier, it was suggested that carotenoids in light-harvesting complexes 2 (LH2) can generate singlet oxygen, further oxidizing bacteriochlorophyll to 3-acetyl-chlorophyll.
