Inorganic Pyrophosphatases: Study of Interest
(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. ...

ZipN is an essential FtsZ membrane tether and contributes to the septal localization of SepJ in the flamentous cyanobacterium Anabaena
(Nature Publishing Group, 2019)
The organismic unit of heterocyst-forming cyanobacteria is a filament of communicating cells connected by septal junctions, proteinaceous structures bridging the cytoplasms of contiguous cells. This distinct bacterial ...

Regulation of K+ Nutrition in Plants
(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 ...

Beta-Cyanoalanine synthase action in root hair elongation is exerted at early steps of the root hair elongation pathway and is independent of direct cyanide inactivation of NADPH oxidase
(Oxford University Press, 2018)
In Arabidopsis thaliana, cyanide is produced concomitantly with ethylene biosynthesis and is mainly detoxified by the ß-cyanoalanine synthase CAS-C1. In roots, CAS-C1 activity is essential to maintain a low level of cyanide ...

Control of autophagy in Chlamydomonas is mediated through redox-dependent inactivation of the ATG4 protease
(American Society of Plant Biologists, 2016)
Autophagy is a major catabolic pathway by which eukaryotic cells deliver unnecessary or damaged cytoplasmic material to the vacuole for its degradation and recycling in order to maintain cellular homeostasis. Control of ...

Two strictly polyphosphate-dependent gluco(manno)kinases from diazotrophic Cyanobacteria with potential to phosphorylate hexoses from polyphosphates
(Springer, 2015)
The single-copy genes encoding putative polyphosphate–glucose phosphotransferases (PPGK, EC 2.7.1.63) from two nitrogen-fixing Cyanobacteria, Nostoc sp. PCC7120 and Nostoc punctiforme PCC73102, were cloned and functionally ...

Signaling by hydrogen sulfide and cyanide through post-translational modification
(Oxford University Press, 2019)
Two cysteine metabolism-related molecules, hydrogen sulfide and hydrogen cyanide, which are considered toxic, have now been considered as signaling molecules. Hydrogen sulfide is produced in chloroplasts through the activity ...

Intrinsically disordered inhibitor of glutamine synthetase is a functional protein with random-coil-like pKa values
(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 ...

Antibacterial activity of plant methanolic extracts on a field isolate of Pseudomonas syringae pv tomato from the Casablanca region (Morocco)
(2013)
A bacterial field isolate recovered from infected to- mato plants in a green-house at Sidi Rehal, a region near Casablanca city (Morocco), was identified as the gammaproteobacterium Pseudomonas syringae pv. to- mato DC3000 ...

Investigating the effect of target of rapamycin kinase inhibition on the Chlamydomonas reinhardtii phosphoproteome: from known homologs to new targets
(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 ...
