The function of the NADPH thioredoxin reductase C-2-Cys peroxiredoxin system in plastid redox regulation and signalling
(Elsevier, 2012)
Protein disulphide–dithiol interchange is a universal mechanism of redox regulation in which thioredoxins (Trxs) play an essential role. In heterotrophic organisms, and non-photosynthetic plant organs, NADPH provides the ...

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 ...

Crop improvement through microbial biofertilisers and molecular markers of salt stress
(2022-03-17)
The exponential growth of the population, the trend towards organic food consumption and the increasingly restrictive regulations imposed by the European Union are forcing the agricultural sector to evolve towards more ...

A New Type of Asymmetrically Acting β-Carotene Ketolase Is Required for the Synthesis of Echinenone in the Cyanobacterium Synechocystis sp. PCC 6803
(Elsevier, 1997)
We have isolated, based on the knowledge of the complete genomic sequence of the cyanobacterium Synechocystis sp. PCC 6803, an open reading frame (slr0088) similar to known bacterial carotene desaturases and have analyzed ...

Genes for asparagine metabolism in Lotus japonicus : differential expression and interconnection with photorespiration
(BioMed Central, 2017)
Background: Asparagine is a very important nitrogen transport and storage compound in plants due to its high nitrogen/carbon ratio and stability. Asparagine intracellu lar concentration depends on a balance between ...

The Functional Relationship between NADPH Thioredoxin Reductase C, 2-Cys Peroxiredoxins, and m-Type Thioredoxins in the Regulation of Calvin–Benson Cycle and Malate-Valve Enzymes in Arabidopsis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-05-03)
The concerted regulation of chloroplast biosynthetic pathways and NADPH extrusion via malate valve depends on f and m thioredoxins (Trxs). The finding that decreased levels of the thiol-peroxidase 2-Cys peroxiredoxin (Prx) ...

Phylogenetic and functional analysis of cyanobacterial Cytochrome c6-like proteins
(Frontiers Media S.A., 2023)
All known photosynthetic cyanobacteria carry a cytochrome c6 protein that acts transferring electrons from cytochrome b6f complex to photosystem I, in photosynthesis, or cytochrome c oxidase, in respiration. In most of the ...

Dual role of HupF in the biosynthesis of [NiFe] hydrogenase in Rhizobium leguminosarum
(BioMed Central, 2012)
Background [NiFe] hydrogenases are enzymes that catalyze the oxidation of hydrogen into protons and electrons, to use H2 as energy source, or the production of hydrogen through proton reduction, as an escape valve for ...

Heterocyst-Specific Transcription of NsiR1, a Non-Coding RNA Encoded in a Tandem Array of Direct Repeats in Cyanobacteria
(Elsevier, 2010)
In response to nitrogen deficiency, some cyanobacteria develop heterocysts, a terminally differentiated cell type, specialized for the fixation of atmospheric nitrogen. In Nostocales, this differentiation process is ...
