NTRC-dependent redox balance of 2-Cys peroxiredoxins is needed for optimal function of the photosynthetic apparatus
(National Academy of Sciences, 2017)
Thiol-dependent redox regulation allows the rapid adaptation of chloroplast function to unpredictable changes in light intensity. Traditionally, it has been considered that chloroplast redox regulation relies on ...

Role of Two Cell Wall Amidases in Septal Junction and Nanopore Formation in the Multicellular Cyanobacterium Anabaena sp. PCC 7120
(Frontiers Media, 2017)
Filamentous cyanobacteria have developed a strategy to perform incompatible processes in one filament by differentiating specialized cell types, N2-fixing heterocysts and CO2-fixing, photosynthetic, vegetative cells. ...

A new member of the thioredoxin reductase family from early uxygenic photosynthetic organisms
(Oxford University Press, 2017)
Thioredoxins (Trxs) are key components of the redox system that regulates the activity of a spectrum of target proteins through dithiol-disulfide exchange reactions. Trxs are reduced by members of the Trx reductase (TR) ...

Monitoring autophagy in the model green microalga chlamydomonas reinhardtii
(MDPI, 2017-10-22)
Autophagy is an intracellular catabolic system that delivers cytoplasmic constituents and organelles in the vacuole. This degradative process is mediated by a group of proteins coded by autophagy-related (ATG) genes that ...

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. ...

Molecular Diffusion through Cyanobacterial Septal Junctions
(American Society for Microbiology, 2017)
Heterocyst-forming cyanobacteria grow as filaments in which intercellular molecular exchange takes place. During the differentiation of N2-fixing heterocysts, regulators are transferred between cells. In the diazotrophic ...

Modelling growth and CO2 fixation by Scenedesmus vacuolatus in continuous culture
(Elsevier, 2017)
A promising approach to CO2 abatement is the use of photosynthetic microorganisms. Different microalgae (Chloroccocum sp., Porphyridium purpureum, Scenedesmus vacuolatus) and cyanobacteria (Anabaena PCC7119, Anabaena ...

Persulfidation proteome reveals the regulation of protein function by hydrogen sulfide in diverse biological processes in Arabidopsis
(Oxford University Press, 2017)
Hydrogen sulfide-mediated signaling pathways regulate many physiological and pathophysiological processes in mammalian and plant systems. The molecular mechanism by which hydrogen sulfide exerts its action involves ...

An event of alternative splicing affects the expression of the NTRC gene, encoding NADPH-thioredoxin reductase C, in seed plants
(Elsevier, 2017)
The NTRCgene encodes aNADPH-dependentthioredoxin reductase with a joint thioredoxin domain, exclusive ofphotosynthetic organisms. An updated search of NTRCgenesshows that althoughmost species harbor a single ...

NADPH Thioredoxin Reductase C and Thioredoxins Act Concertedly in Seedling Development
(American Society of Plant Biologists, 2017)
Thiol-dependent redox regulation of enzyme activity plays a central role in the rapid acclimation of chloroplast metabolism to ever-fluctuating light availability. This regulatory mechanism relies on ferredoxin reduced ...
