Dynamics–Function Correlation in Photosystem II: Molecular Dynamics in Solution

Crystals, 2023
A detailed comprehension of protein function requires information on the spatial structure of the protein, which is often gathered from X-ray crystallography.

High-resolution model of Arabidopsis Photosystem II reveals the structural consequences of digitonin-extraction

Scientific Reports, 2021
In higher plants, the photosynthetic process is performed and regulated by Photosystem II (PSII). Arabidopsis thaliana was the first higher plant with a fully sequenced genome, conferring it the status of a model organism; nonetheless, a high-resolution ...

Rapeseed (Brassica napus) Mitogen-Activated Protein Kinase 1 Enhances Shading Tolerance by Regulating the Photosynthesis Capability of Photosystem II

Frontiers in Plant Science, 2022
Rapeseed (Brassica napus) is the third-largest source of vegetable oil in the world with an edible, medicinal, and ornamental value. However, insufficient light or high planting density directly affects its growth, development, yield, and quality ...

Photosynthetic Production of Molecular Oxygen by Water Oxidation

Oxygen, 2022
This review deals with the production of oxygen by photo-oxidation of water, which is a topic fitting a journal devoted to oxygen. Most of the present biosphere, including mankind, depends on oxygen. Elucidating the mechanism is of importance for solving

Formation of singlet oxygen by decomposition of protein hydroperoxide in photosystem II. [PDF]

PLoS ONE, 2017
Singlet oxygen (1O2) is formed by triplet-triplet energy transfer from triplet chlorophyll to O2 via Type II photosensitization reaction in photosystem II (PSII). Formation of triplet chlorophyll is associated with the change in spin state of the excited

Acyl lipids in the supramolecular chlorophyll-protein complexes of photosystems - isolation artifacts or integral components regulating their structure and functions?

Acta Societatis Botanicorum Poloniae, 2014
The precise nature of interactions between the chloropnyll-protein complexes related to photosystem I or photosystem II and the acyl lipids in the thylakoid membranes is not yet fully elucidated.

Reconstructing the origin of oxygenic photosynthesis: do assembly and photoactivation recapitulate evolution?

Frontiers in Plant Science, 2016
Due to the great abundance of genomes and protein structures that today span a broad diversity of organisms, now more than ever before, it is possible to reconstruct the molecular evolution of protein complexes at an incredible level of detail.
