N-Terminal Lipid Modification Is Required for the Stable Accumulation of CyanoQ in Synechocystis sp. PCC 6803. [PDF]

PLoS ONE, 2016
The CyanoQ protein has been demonstrated to be a component of cyanobacterial Photosystem II (PS II), but there exist a number of outstanding questions concerning its physical association with the complex.

Biochemical and biotechnological approaches as basis for structure determination of pigment-protein complexes of oxygenic photosynthesis [PDF]

, 2009
Today the structure of photosystem II, which is the enzyme responsible for the evolution of molecular oxygen by plants, algae and cyanobacteria, is known up to a resolution of about 3.0 Å in cyanobacteria (Loll et al., 2005).

Heavy Metal Contamination: Impacts From Plants to the Food Chain and Eco‐Friendly Amelioration Strategies

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Heavy metal pollution reduces soil health and threatens food safety by entering plants; however, the use of nanoparticles, biofertilizers, and organic fertilizers such as biochar offers a promising strategy for improvement and sustainable agriculture. ABSTRACT Heavy metal (HM) pollution, resulting from human activities such as mining and the excessive ...

The Effects of Soil Salinity on Photosystem II of Rice Seedlings

Guan'gai paishui xuebao, 2022
【Objective】 Photosystem II (water-plastoquinone oxidoreductase) is a protein complex in light-dependent reactions of oxygenic photosynthesis. The purpose of this paper is to study the effect of salt stress on photosystem II of rice seedlings. 【Method】 We

The PsbP Protein Is Required for Photosystem II Complex Assembly/Stability and Photoautotrophy in Arabidopsis thaliana [PDF]

Journal of Biological Chemistry, 2007
Interfering RNA was used to suppress the expression of the genes At1g06680 and At2g30790 in Arabidopsis thaliana, which encode the PsbP-1 and PsbP-2 proteins, respectively, of photosystem II (PS II). A phenotypic series of transgenic plants was recovered that expressed intermediate and low amounts of PsbP. Chlorophyll fluorescence induction and Q(A)(-)

Three dimensional structure of the light-harvesting chlorophyll a/b protein complex from plant chloroplasts [PDF]

, 2002
The light-harvesting chlorophyll a/b protein complex (LHC-II) is the major collector of solar energy in all plants and it binds about half of the chlorophyll in green plants.

Picosecond fluorescence of intact and dissolved PSI-LHCI crystals [PDF]

, 2008
Over the last years many crystal structures of photosynthetic pigment-protein complexes have been determined, and used extensively to model spectroscopic results obtained on the same proteins in solution. However, the crystal structure is not necessarily

Assembly of the Photosystem II Membrane-Protein Complex of Oxygenic Photosynthesis

, 2017
Photosystem II is a 700-kDa membrane-protein super-complex responsible for the light-driven splitting of water in oxygenic photosynthesis. The photosystem is comprised of two 350-kDa complexes each made of 20 different polypeptides and over 80 co-factors.

Structural basis for an early stage of the photosystem II repair cycle in Chlamydomonas reinhardtii

Nature Communications
Photosystem II (PSII) catalyzes water oxidation and plastoquinone reduction by utilizing light energy. It is highly susceptible to photodamage under high-light conditions and the damaged PSII needs to be restored through a process known as the PSII ...

Going around the Kok cycle of the water oxidation reaction with femtosecond X-ray crystallography

IUCrJ, 2023
The water oxidation reaction in photosystem II (PS II) produces most of the molecular oxygen in the atmosphere, which sustains life on Earth, and in this process releases four electrons and four protons that drive the downstream process of CO2 fixation ...
