Loss of mature D1 leads to compromised CP43 assembly in Arabidopsis thaliana [PDF]
Background Photosystem II (PSII) is a highly conserved integral-membrane multi-subunit pigment-protein complex. The proteins, pigments, lipids, and ions in PSII need to be assembled precisely to ensure a proper PSII biogenesis.

Light stability of the isolated CP43 studied by infrared and terahertz spectroscopy [PDF]
Here, the light-induced changes of the core antenna complex chlorophyll protein 43 (CP43) isolated from PSII of spinach were assessed using infrared and terahertz (THz) spectroscopy.

Pre-Chilling CGA Application Alleviates Chilling Injury in Tomato by Maintaining Photosynthetic Efficiency and Altering Phenylpropanoid Metabolism [PDF]
Chilling injury can limit the productivity of tomato (Solanum lycopersicum L.), especially in over-wintering greenhouse. We here explored the effect of the pre-application of chlorogenic acid (CGA) in mitigating the impact of chilling on tomato ...

Revealing the structure of the photosystem II chlorophyll binding proteins, CP43 and CP47
A review of the structural properties of the photosystem II chlorophyll binding proteins, CP47 and CP43, is given and a model of the transmembrane helical domains of CP47 has been constructed. The model is based on (i) the amino acid sequence of the spinach protein, (ii) an 8 A three-dimensional electron density map derived from electron ...

Excitation landscape of the CP43 photosynthetic antenna complex from multiscale simulations. [PDF]
QM/MM simulations and the perturbed matrix method are used to investigate a crucial photosynthetic antenna complex, mapping its global excitonic structure and revealing the presence of a low-lying charge transfer state.

In silico and bioassay-guided identification of potential anti-SARS-CoV-2 tentative candidate compounds from Andrographis paniculata extract [PDF]
COVID-19, caused by the SARS-CoV-2 virus. This infectious disease significantly targets the upper and lower respiratory tracts of humans and animals. The mechanisms of SARS-CoV-2 infection are crucially mediated by specific viral proteins, such as the ...

Spectroscopic Study of the CP43′ Complex and the PSI–CP43′ Supercomplex of the Cyanobacterium Synechocystis PCC 6803 [PDF]
The PSI-CP43' supercomplex of the cyanobacterium Synechocystis PCC 6803, grown under iron-starvation conditions, consists of a trimeric core Photosystem I (PSI) complex and an outer ring of 18 CP43' light-harvesting complexes. We have investigated the electronic structure and excitation energy transfer (EET) pathways within the CP43' (also known as the

Light-induced oxidative stress, N-formylkynurenine, and oxygenic photosynthesis. [PDF]
Light stress in plants results in damage to the water oxidizing reaction center, photosystem II (PSII). Redox signaling, through oxidative modification of amino acid side chains, has been proposed to participate in this process, but the oxidative signals
