High light-induced changes in whole-cell proteomic profile and its correlation with the organization of thylakoid super-complex in cyclic electron transport mutants of Chlamydomonas reinhardtii

Frontiers in Plant Science, 2023
Light and nutrients are essential components of photosynthesis. Activating the signaling cascades is critical in starting adaptive processes in response to high light.

Biogeography of photosynthetic light-harvesting genes in marine phytoplankton. [PDF]

PLoS ONE, 2009
BACKGROUND: Photosynthetic light-harvesting proteins are the mechanism by which energy enters the marine ecosystem. The dominant prokaryotic photoautotrophs are the cyanobacterial genera Prochlorococcus and Synechococcus that are defined by two distinct ...

The Assembly of Super-Complexes in the Plant Chloroplast

Biomolecules, 2021
Increasing evidence has revealed that the enzymes of several biological pathways assemble into larger supramolecular structures called super-complexes. Indeed, those such as association of the mitochondrial respiratory chain complexes play an essential ...

Preprocess dependence of optical properties of ensembles and single siphonaxanthin-containing major antenna from the marine green alga Codium fragile

Scientific Reports, 2022
The siphonaxanthin-siphonein-Chl-a/b-protein (SCP) is the light-harvesting complex of the marine alga Codium fragile. Its structure resembles that of the major light-harvesting complexes of higher plants, LHC II, yet it features a reversed Chl a:Chl b ...

A different perspective for nonphotochemical quenching in plant antenna complexes

Nature Communications, 2021
Nonphotochemical quenching (NPQ) protects photosynthetic complexes from damage due to excess light. Here the authors explore different conformations of the plant CP29 light harvesting complex, showing how protein tuning of carotenoid excitation energies ...

Photosynthetic Light Harvesting and Thylakoid Organization in a CRISPR/Cas9 Arabidopsis Thaliana LHCB1 Knockout Mutant

Frontiers in Plant Science, 2022
Light absorbed by chlorophylls of Photosystems II and I drives oxygenic photosynthesis. Light-harvesting complexes increase the absorption cross-section of these photosystems.

Optical cavity-mediated exciton dynamics in photosynthetic light harvesting 2 complexes

Nature Communications, 2022
Light-matter interaction can induce changes to the properties of the system by creating hybrid collective states of light and molecular excitations, the so called polaritons.

Proteoliposomes for Studying Lipid-protein Interactions in Membranes in vitro

Bio-Protocol, 2021
Lipids in biomembranes can control the structure and, therefore, the functionality of membrane-embedded protein complexes. Unraveling how the lipid composition determines the mode of operation of membrane proteins provides mechanistic insights into their
