Mitochondrial thiol-disulfide system under acute hypoxia and hypoxic-hyperoxic adaptation [PDF]
The authors investigated the state of mitochondrial glutathione pool (reduced and oxidized glutathione, protein-GSH mixed disulfides), content of carbonyl groups and free sulfhydryl groups of proteins, protein expression of key mitochondrial antioxidant ...

Selenium in biology: Facts and medical perspectives [PDF]
Several decades after the discovery of setenium as an essential trace element in vertebrates approximately 20 eukaryotic and more than 15 prokaryotic selenoproteins containing the 21(st) proteinogenic amino acid, selenocysteine, have been identified ...

CydDC-mediated reductant export in Escherichia coli controls the transcriptional wiring of energy metabolism and combats nitrosative stress [PDF]
The glutathione/cysteine exporter CydDC maintains redox balance in Escherichia coli. A cydD mutant strain was used to probe the influence of CydDC upon reduced thiol export, gene expression, metabolic perturbations, intracellular pH homeostasis, and ...

Geminivirus C2 protein represses genes involved in sulphur assimilation and this effect can be counteracted by jasmonate treatment [PDF]
Geminiviruses are plant viruses that infect a broad range of crops and cause extensive losses worldwide, having an important economic impact. C2, a multifunctional pathogenicity factor encoded by geminiviruses, has been recently shown to suppress the ...

Adaptive response to oxidative stress in the filamentous fungus Aspergillus niger B1-D [PDF]
In the present study, we used a recombinant filamentous fungus strain, Aspergillus niger B1-D, as a model system, and investigated the antioxidant defences in this organism.
