Characterization of CP43 and PIF1 GWAS Selected Candidate Genes in Medicago truncatula and their Contribution to Rhizobia Symbiosis and Phenotypes of Interest Using an hpRNA Based RNAi Platform [PDF]

, 2015
Medicago truncatula is a model organism used to study the symbiotic relationship between plants and nitrogen fixing soil bacteria of the genus rhizobia. By studying the genes that are involved in this symbiosis we can accomplish the goal of transplanting

Predicted locations of NFK modifications, NFK365-CP43 and NFK317-D1, in the T. vulcanus PSII structure [2].

, 2012
The OEC is shown in black, grey, and red. P680 and YZ (green spacefill) are shown above the OEC. The CP43 and D1 backbones are displayed in pink and green, respectively. The side chain of Trp-365 in CP43 is in red spacefill.

In silico and bioassay-guided identification of potential anti-SARS-CoV-2 tentative candidate compounds from Andrographis paniculata extract

Computational and Structural Biotechnology Journal
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 ...

Participation of Glutamate-354 of the CP43 Polypeptide in the Ligation of Mn and the Binding of Substrate Water in Photosystem II [PDF]

, 2011
In the current X-ray crystallographic structural models of photosystem II, Glu354 of the CP43 polypeptide is the only amino acid ligand of the oxygen-evolving Mn4Ca cluster that is not provided by the D1 polypeptide.

Letter to Nature. Iron deficiency induces the formation of an antenna ring around trimeric photosystem I in cyanobacteria.

, 2001
Although iron is the fourth most abundant element in the Earth's crust, its concentration in the aquatic ecosystems-particularly the open oceans-is sufficiently low to limit photosynthetic activity and phytoplankton growth.

Spectroscopic properties of the CP43 core antenna protein of photosystem

, 1999
CP43 is a chlorophyll-protein complex that funnels excitation energy from the main light-harvesting system of photosystem II to the photochemical reaction center.

利用超快时间分辨技术对光系统II核心天线CP43和CP47的动力学荧光光谱的分析

, 2001
Ultrafast time-resolved fluorescence experiments have been performed with core antennas CP43 and CP47 of PS II. Their dynamic fluorescence spectra were obtained with excitation wavelength 514.5 mn. For CP43, the emission spectrum was found to be from 640

The contribution of CP43:Phe345 to the oxygen-evolving complex of Photosystem II is essential for stable water splitting

Biochemical and Biophysical Research Communications
Water splitting by Photosystem II (PS II) in photosynthesis is catalyzed by a Mn4CaO5 oxygen-evolving complex (OEC). The reaction center D1 protein provides most of the ligands to the OEC but its complete assembly requires the association of the CP43 core antenna subunit which provides CP43:Glu341 as an essential ligand.
