NTRC Plays a Crucial Role in Starch Metabolism, Redox Balance, and Tomato Fruit Growth [Article]
(American Society of Plant Biologists, 2019)NADPH-thioredoxin reductase C (NTRC) forms a separate thiol-reduction cascade in plastids, combining both NADPHthioredoxin reductase and thioredoxin activities on a single polypeptide. While NTRC is an important regulator ...

Cyt c6-3: A new isoform of photosynthetic Cyt c6 exclusive to heterocyst-forming cyanobacteria [Article]
(Oxford University Press, 2017)All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the Cyt b6 f complex to PSI, although it is also involved in respiration. We have previously ...

Intrinsically disordered inhibitor of glutamine synthetase is a functional protein with random-coil-like pKa values [Article]
(Wiley-Blackwell, 2017)The sequential action of glutamine synthetase (GS) and glutamate synthase (GOGAT) in cyanobacteria allows the incorporation of ammonium into carbon skeletons. In the cyanobacterium Synechocystis sp. PCC 6803, the activity ...

Hydrogen sulfide regulates the cytosolic/nuclear partitioning of glyceraldehyde-3-phosphate dehydrogenase by enhancing its nuclear localization [Article]
(Oxford University Press, 2017)Hydrogen sulfide is an important signaling molecule comparable with nitric oxide and hydrogen peroxide in plants. The underlying mechanism of its action is unknown, although it has been proposed to be S-sulfhydration. This ...

Virus-induced gene silencing database for phenomics and functional genomics in Nicotiana benthamiana [Article]
(Wiley-Blackwell, 2018)Virus-induced gene silencing (VIGS) is an important forward and reverse genetics method for the study of gene function in many plant species, especially Nicotiana benthamiana. However, despite the widespread use of VIGS, ...

The ancient phosphatidylinositol 3-kinase signaling system is a master regulator of energy and carbon metabolism in algae [Article]
(American Society of Plant Biologists, 2018)Algae undergo a complete metabolic transformation under stress by arresting cell growth, inducing autophagy and hyperaccumulating biofuel precursors such as triacylglycerols and starch. However, the regulatory mechanisms ...

Chloroplast damage induced by the inhibition of fatty acid synthesis triggers autophagy in chlamydomonas [Article]
(American Society of Plant Biologists, 2018)Fatty acids are synthesized in the stroma of plant and algal chloroplasts by the fatty acid synthase complex. Newly synthesized fatty acids are then used to generate plastidial lipids that are essential for chloroplast ...

The NADPH-Dependent thioredoxin reductase C-2-Cys peroxiredoxin redox system modulates the activity of thioredoxin x in arabidopsis chloroplasts [Article]
(Oxford University Press, 2018)The chloroplast redox network is composed of a complex set of thioredoxins (Trxs), reduced by ferredoxin (Fdx) via a Fdx-dependent Trx reductase (FTR), and an NADPH-dependent Trx reductase with a joint Trx domain, NTRC, ...

Investigating the effect of target of rapamycin kinase inhibition on the Chlamydomonas reinhardtii phosphoproteome: from known homologs to new targets [Article]
(Blackwell Publishing Ltd, 2019)Target of rapamycin (TOR) kinase is a conserved regulator of cell growth whose activity is modulated in response to nutrients, energy and stress. Key proteins involved in the pathway are conserved in the model photosynthetic ...

2-Cys Peroxiredoxins Participate in the Oxidation of Chloroplast Enzymes in the Dark [Article]
(Elsevier, 2018)Most redox-regulated chloroplast enzymes are reduced during the day and oxidized during the night. While the reduction mechanism of light-dependent enzymes is well known, the mechanism mediating their oxidation in the dark ...

Regulation of K+ Nutrition in Plants [Article]
(Frontiers Media, 2019)Modern agriculture relies on mineral fertilization. Unlike other major macronutrients, potassium (K+) is not incorporated into organic matter but remains as soluble ion in the cell sap contributing up to 10% of the dry ...

Cell stress by phosphate of two protozoa tetrahymena thermophila and tetrahymena pyriformis [Article]
(Scientific Research Publishing, 2017)Phosphorus is one of the bioelements most needed as a compound cell by living organisms. Phosphorus is involved in several pathologies: in human with bone and kidney diseases, in mammals with metabolism disorder (glucose, ...

Inorganic Pyrophosphatases: Study of Interest [Article]
(Scientific Research Publishing, 2017)Inorganic pyrophosphatases are enzymes that catalyze the hydrolysis of inorganic pyrophosphate to orthophosphate. These enzymes are divided into two groups: the soluble pyrophosphatases and the membrane pyrophosphatases. ...

N-terminal chimaeras with signal sequences enhance the functional expression and alter the subcellular localization of heterologous membrane-bound inorganic pyrophosphatases in yeast [Article]
(Portland Press, 2010)Expression of heterologous multispanning membrane proteins in Saccharomyces cerevisiae is a difficult task. Quite often, the use of multicopy plasmids where the foreign gene is under the control of a strong promoter does ...

The ciliate protist tetrahymena pyriformis as a cellular adhesion model for the pathogenic bacterium staphylococcus aureus [Article]
(Scientific Research Publishing, 2017)Staphylococcus aureus is one of the main pathogenic agents responsible for nosocomial and community-acquired bacterial infections. The pathogenicity of this Gram-positive bacterium is ensured by its different adhesion ...

Intracellular proton pumps as targets in chemotherapy: V-ATPases and cancer [Article]
(Bentham Science Publishers, 2012)Cancer cells show a metabolic shift that makes them overproduce protons; this has the potential to disturb the cellular acid-base homeostasis. However, these cells show cytoplasmic ...
