Carotenoids can dissipate excess energy captured by photosynthetic light-harvesting complexes to prevent photodamage. Here, via spectroscopic and in silico approaches, Liguori et al. resolve different carotenoid dark states and propose conformational

The origin of pigment-binding differences in CP29 and LHCII: the role of protein structure and dynamics

Autor: Eduard Elias, Nicoletta Liguori, Roberta Croce

Publikováno v: Photochemical & Photobiological Sciences.

The first step of photosynthesis in plants is performed by the light-harvesting complexes (LHC), a large family of pigment-binding proteins embedded in the photosynthetic membranes. These complexes are conserved across species, suggesting that each h

Increasing the absorption cross section of plants by introducing far-red absorbing chlorophylls (Chls) has been proposed as a strategy to boost crop yields. To make this strategy effective, these Chls should bind to the photosynthetic complexes witho

Under strong sunlight, plants avoid photooxidation by quenching the excess absorbed energy. Quenching is triggered by PsbS, a membrane protein that is activated and deactivated by the light-dependent pH changes in the thylakoid lumen. The mechanism o

In plants and green algae, light-harvesting complexes (LHCs) are a large family of chlorophyll binding proteins functioning as antennae, collecting solar photons and transferring the absorbed energy to the photosynthetic reaction centers, where light
