Intracellular proton pumps as targets in chemotherapy: V-ATPases and cancer
(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 ...

The N-terminal Part of Arabidopsis thaliana Starch Synthase 4 Determines the Localization and Activity of the Enzyme
(American Society for Biochemistry and Molecular Biology, 2016)
Starch synthase 4 (SS4) plays a specific role in starch synthesis because it controls the number of starch granules synthesized in the chloroplast and is involved in the initiation of the starch granule. We showed previously ...

Inorganic pyrophosphatase defects lead to cell cycle arrest and autophagic cell death through NAD+ depletion in fermenting yeast
(Elsevier, 2013)
Inorganic pyrophosphatases are required for anabolism to take place in all living organisms. Defects in genes encoding these hydrolytic enzymes are considered inviable, although their exact nature has not been studied at ...

A universal stress protein involved in oxidative stress1 is a phosphorylation target for protein kinase CIPK6
(American Society of Plant Biologists, 2017)
Calcineurin B-like interacting protein kinases (CIPKs) decode calcium signals upon interaction with the calcium sensors calcineurin B like proteins into phosphorylation events that result into adaptation to environmental ...

Cysteine-generated sulfide in the cytosol negatively regulates autophagy and modulates the transcriptional profile in arabidopsis
(American Society of Plant Biologists, 2012)
In Arabidopsis thaliana, DES1 is the only identified l-Cysteine desulfhydrase located in the cytosol, and it is involved in the degradation of cysteine and the concomitant production of H2S in this cell compartment. Detailed ...

S-sulfocysteine synthase function in sensing chloroplast redox status
(Taylor & Francis, 2013)
The minor chloroplastic O-acetylserine(thiol)lyase isoform encoded by the CS26 gene in Arabidopsis thaliana has been described as an S-sulfocysteine synthase enzyme that plays an important role in chloroplast function. ...

Assessment of the CO2 fixation capacity of Anabaena sp. ATCC 33047 outdoor cultures in vertical flat-panel reactors
(Elsevier, 2014)
The extent of biological CO2 fixation was evaluated for outdoor cultures of the cyanobacterium Anabaena sp. ATCC 33047. Culture conditions were optimized indoors in bubble-column photochemostats operating in continuous ...

Upstream kinases of plant SnRKs are involved in salt stress tolerance
(Wiley, 2018)
Sucrose non-fermenting 1-related protein kinases (SnRKs) are important for plant growth and stress responses. This family has three clades: SnRK1, SnRK2 and SnRK3. Although plant SnRKs are thought to be activated by upstream ...

Septal protein SepJ from the heterocyst‐forming cyanobacterium Anabaena forms multimers and interacts with peptidoglycan
(Wiley Open Access, 2017)
Heterocyst‐forming cyanobacteria grow as filaments that can be hundreds of cells long. Proteinaceous septal junctions provide cell–cell binding and communication functions in the filament. In Anabaena sp. strain PCC 7120, ...

Cell stress by phosphate of two protozoa tetrahymena thermophila and tetrahymena pyriformis
(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, ...
