Photosystem I (PSI) is a major player in the light reactions of photosynthesis. In higher plants, it consists of a core complex and four external antennae, Lhca1–4 forming the PSI–light-harvesting complex I (LHCI) supercomplex. The protein and pigment composition as well as the spectroscopi...
The main function of the antenna (the light-harvesting complex) is to transfer excitation energy to the photosynthetic reaction centers (see a review [125]). Besides the transfer of excitons from excited antenna chlorophylls to the reaction centers (leading to photochemistry), part of the ...
Control of the light-harvesting function of chloroplast membranes by aggregation of the LHCII chlorophyll-protein complex. A new hypothesis is presented to explain the major molecular process that regulates the efficiency of light harvesting by chloroplast membranes. It is prop... P Horton,AV Ruban...
Here, we employ femtosecond transient absorption spectroscopy to study energy transfer pathways in the intrinsic light-harvesting complex (LHC) of dinoflagellates, which contains the carbonyl carotenoid peridinin. Carotenoid to chlorophyll energy transfer efficiency is about 90% in the 530−550 nm ...
Unlike most light-harvesting antenna complexes, the phycobilisome is not an integral membrane complex but is attached to the surface of the photosynthetic membranes. It is composed of both the pigmented phycobiliproteins and the nonpigmented linker polypeptides; the former are important for absorbing...

The effect of the incorporation of the major light-harvesting complex of photosystem II (LHCII) to planar bilayer lipid membranes (BLMs) formed from soybean asolectin and unilamellar small liposomes formed from egg-yolk phosphatidylcholine on ion transport across the lipid bilayer has been studied....
The degradation of the most abundant membrane protein on Earth, the light-harvesting complex of Photosystem II LHC II, is highly regulated under different environmental conditions,e.g.light stress, to prevent photochemical damage of the reaction center. However, despite major effort to identify the ...
