Thioredoxin system modulates metabolic and stomatal responses to elevated CO2 in Arabidopsis

New Phytologist, EarlyView.
Integrative model of extraplastidial NADPH‐dependent thioredoxin reductase/thioredoxin system‐mediated regulation of stomatal function, redox homeostasis, and metabolic responses under ambient and elevated CO2 in Arabidopsis thaliana. Summary The NADPH‐dependent thioredoxin reductase/thioredoxin (NTR/TRX) system plays a central role in maintaining ...

Identification and characterization of drought-responsive CC-type glutaredoxins from cassava cultivars reveals their involvement in ABA signalling

BMC Plant Biology, 2018
Background CC-type glutaredoxins (GRXs) are plant-specific glutaredoxin, play regulatory roles in response of biotic and abiotic stress. However, it is not clear whether the CC-type GRXs are involve in drought response in cassava (Manihot esculenta), an ...

Hyperglycaemia‐induced reactive oxygen species production in cardiac ventricular myocytes differs among mammals

The Journal of Physiology, EarlyView.
Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Evolution based on domain combinations: the case of glutaredoxins

BMC Evolutionary Biology, 2009
Background Protein domains represent the basic units in the evolution of proteins. Domain duplication and shuffling by recombination and fusion, followed by divergence are the most common mechanisms in this process.

Microbial Oxidative Stress in Food Fermentations: A Comprehensive Review

eFood, Volume 7, Issue 4, August 2026.
Oxidative stress has a dual role in food fermentations: low ROS supports adaptive signaling, whereas excessive ROS causes cellular damage and process inhibition. Managing redox state as a controllable process variable can improve fermentation robustness and final food quality.

Substrate specificity of thioredoxins and glutaredoxins – towards a functional classification

Heliyon, 2019
The spatio-temporal reduction and oxidation of protein thiols is an essential mechanism in signal transduction in all kingdoms of life. Thioredoxin (Trx) family proteins efficiently catalyze thiol-disulfide exchange reactions and the proteins are widely ...

Structural analysis of glutaredoxin domain of Mus musculus thioredoxin glutathione reductase. [PDF]

PLoS ONE, 2012
Thioredoxin glutathione reductase (TGR) is a member of the mammalian thioredoxin reductase family that has a monothiol glutaredoxin (Grx) domain attached to the thioredoxin reductase module.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, Volume 49, Issue 8, Page 5849-5865, August 2026.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

The structure of a reduced mutant T4 glutaredoxin [PDF]

FEBS Letters, 1995
The mutant T4 glutaredoxin where the active site residues Val15 and Tyr16 have been substituted by Gly and Pro, respectively, crystallizes in a form where the active site disulfide is accessible to reagents. Treatment of the crystals with dithiotreitol causes very subtle changes in the overall glutaredoxin structure.
