One-step isolation and biochemical characterization of a highlyactive plant PSII monomeric core

open access: yes, 2011
We describe a one-step detergent solubilization protocol for isolating a highly active form of Photosystem II (PSII) from Pisum sativum L. Detailed characterization of the preparation showed that the complex was a monomer having no light harvesting ...

Arabidopsis STN7 Kinase Provides a Link between Short- and Long-Term Photosynthetic Acclimation [PDF]

open access: yes, 2009
Flowering plants control energy allocation to their photosystems in response to light quality changes. This includes the phosphorylation and migration of light-harvesting complex II (LHCII) proteins (state transitions or short-term response) as well as ...

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

open access: yesFood Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Multiple impacts of loss of plastidic phosphatidylglycerol biosynthesis on photosynthesis during seedling growth of Arabidopsis

open access: yesFrontiers in Plant Science, 2016
Phosphatidylglycerol (PG) is the only major phospholipid in the thylakoid membrane in cyanobacteria and plant chloroplasts. Although PG accounts only for ~10% of total thylakoid lipids, it plays indispensable roles in oxygenic photosynthesis. In contrast

Cytoplasmic N-Terminal Protein Acetylation Is Required for Efficient Photosynthesis in Arabidopsis [PDF]

open access: yes, 2003
The Arabidopsis atmak3-1 mutant was identified on the basis of a decreased effective quantum yield of photosystem II. In atmak3-1, the synthesis of the plastome-encoded photosystem II core proteins D1 and CP47 is affected, resulting in a decrease in the ...

Data_Sheet_1_Diversity Among Cyanobacterial Photosystem I Oligomers.docx

open access: yes, 2022
Unraveling the oligomeric states of the photosystem I complex is essential to understanding the evolution and native mechanisms of photosynthesis. The molecular composition and functions of this complex are highly conserved among cyanobacteria, algae ...

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

open access: yesJournal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

A two-component regulatory system in transcriptional control of photosystem stoichiometry: redox-dependent and sodium ion-dependent phosphoryl transfer from cyanobacterial histidine kinase Hik2 to response regulators Rre1 and RppA

open access: yesFrontiers in Plant Science, 2016
I hereby submit the above-titled manuscript for publication in Frontiers in Plant Science. The research reported is original and novel. No part of it is submitted for publication elsewhere.We report on regulation and interactions of a unique histidine ...

From Mn(II)3 to Mn(IV)3: Controlled Multielectron Oxidation and Hydrocarbon Oxygenation Within a 7‐Dipy Trinuclear Scaffold

open access: yesJournal of the Chinese Chemical Society, EarlyView.
A trinuclear manganese complex supported by the 7‐Dipy scaffold undergoes controlled multielectron oxidation from Mn(II)3 to high‐valent Mn(IV)3 states. Spectroscopic signatures, including 16‐line and geff ≈ 5 EPR features, reveal stepwise redox accumulation. The oxidized Mn3 cluster mediates efficient oxygen‐atom transfer to strong CH bonds, enabling

Consequences of Decreased Light Harvesting Capability on Photosystem II Function in Synechocystis sp. PCC 6803

open access: yesLife, 2014
Cyanobacteria use large pigment-protein complexes called phycobilisomes to harvest light energy primarily for photosystem II (PSII). We used a series of mutants with partial to complete reduction of phycobilisomes to examine the effects of antenna ...
