Inhibition of ferredoxin: NADP+ reductase activity by the hexacyanochromate (III) ion

open access: yesBiochemical and Biophysical Research Communications, 1986
The small inorganic complex Cr(CN)6(3-) is a clean inhibitor of the ferredoxin: NADP+ reductase-catalysed oxidation of reduced spinach ferredoxin by NADP+. Independent spectrophotometric measurements show that millimolar additions of Cr(CN)6(3-) to mixtures of ferredoxin and ferredoxin NADP+ reductase give a marked attenuation of the difference ...

Short Exposure to Full Moonlight Has a Long‐Term Impact on Brassica juncea Cell Activity and Growth

open access: yesPlant, Cell &Environment, Volume 48, Issue 5, Page 3038-3051, May 2025.
ABSTRACT Lunar farming, often regarded as a myth, is regularly practiced in many places around the world (e.g., India) where framers organized their agricultural activities according to moon phases. Early and recent work showed that exposure to moonlight affects the life cycle of plants, from seed germination and vegetative growth to fruit maturation ...

Reaction of the desulfoferrodoxin from Desulfoarculus baarsii with superoxide anion. Evidence for a superoxide reductase activity [PDF]

open access: yesThe journal of biological chemistry, American Society for Biochemistry and Molecular Biology, 2000, 275, pp.115-21, 2014
Desulfoferrodoxin is a small protein found in sulfate-reducing bacteria that contains two independent mononuclear iron centers, one ferric and one ferrous. Expression of desulfoferrodoxin from Desulfoarculus baarsii has been reported to functionally complement a superoxide dismutase deficient Escherichia coli strain.

Genetic alteration of ferredoxin NADP+-reductase or cysteine desulfurase in piperaquine-resistant Plasmodium berghei restores susceptibility to lumefantrine and abolishes the impact of probenecid, verapamil, and cyproheptadine

open access: yes, 2020
Chemotherapy remains central in the control of malaria; however, resistance has consistently thwarted these efforts. Currently, lumefantrine (LM), and piperaquine (PQ) drugs, are essential components in the mainstay artemisinin-based therapies used for ...

Nitrogen Assimilation Plays a Role in Balancing the Chloroplastic Glutathione Redox Potential Under High Light Conditions

open access: yesPlant, Cell &Environment, Volume 48, Issue 5, Page 3559-3572, May 2025.
ABSTRACT Nitrate reduction requires reducing equivalents produced by the photosynthetic electron transport chain. Therefore, it has been suggested that nitrate assimilation provides a sink for electrons under high light conditions. We tested this hypothesis by monitoring photosynthetic efficiency and the chloroplastic glutathione redox potential (chl ...

Regulation of Ferredoxin-NADP+ Oxidoreductase to Cyclic Electron Transport in High Salinity Stressed Pyropia yezoensis

open access: yesFrontiers in Plant Science, 2018
Pyropia yezoensis can survive the severe water loss that occurs during low tide, making it an ideal species to investigate the acclimation mechanism of intertidal seaweed to special extreme environments.

Label-Free Quantitative Proteomics Analysis in Susceptible and Resistant Brassica napus Cultivars Infected with Xanthomonas campestris pv. campestris

open access: yesMicroorganisms, 2021
Black rot, caused by Xanthomonas campestris pv. campestris (Xcc), is the main disease of cruciferous vegetables. To characterize the resistance mechanism in the Brassica napus–Xcc pathosystem, Xcc-responsive proteins in susceptible (cv.

Hydrogen bonding to the cysteine ligand of superoxide reductase: acid--base control of the reaction intermediates [PDF]

open access: yesJournal of biological inorganic chemistry : JBIC : a publication of the Society of Biological Inorganic Chemistry, 2013, 18, pp.815 - 830, 2015
Superoxide reductase SOR is a non-heme iron metalloenzyme that detoxifies superoxide radical in microorganisms. Its active site consists of an unusual non-heme Fe2+ center in a [His4 Cys1] square pyramidal pentacoordination, with the axial cysteine ligand proposed to be an essential feature in catalysis.

Moderate Temperature Reduction Changes the High‐Light Acclimation Strategy of Lettuce Plants

open access: yesPhysiologia Plantarum, Volume 177, Issue 3, May/June 2025.
ABSTRACT In nature, environmental conditions are constantly changing, requiring plants to have numerous regulatory mechanisms to keep light harvesting and metabolism in balance. Here, we show that high light (HL) induces a much stronger non‐photochemical quenching (NPQ) when lettuce plants are exposed to 1500 μmol photons m−2 s−1 for 4 h at 13°C (low ...

Overexpression of the protein disulfide isomerase AtCYO1 in chloroplasts slows dark-induced senescence in Arabidopsis

open access: yesBMC Plant Biology, 2018
Background Chlorophyll breakdown is the most obvious sign of leaf senescence. The chlorophyll catabolism pathway and the associated proteins/genes have been identified in considerable detail by genetic approaches combined with stay-green phenotyping ...
