Cysteine is one of the least abundant amino acids, yet it is frequently found as a highly
conserved residue within functional (regulatory, catalytic, or binding) sites in proteins. It is …

Selenium is an essential micronutrient with important functions in human health and
relevance to several pathophysiological conditions. The biological effects of selenium are …

Peroxiredoxins (Prxs) are a ubiquitous family of cysteine-dependent peroxidase enzymes
that play dominant roles in regulating peroxide levels within cells. These enzymes, often …

Oxidative stress plays an important role in the degeneration of dopaminergic neurons in
Parkinson's disease (PD). Disruptions in the physiologic maintenance of the redox potential …

Chloroplasts communicate information by signalling to nuclei during acclimation to
fluctuating light. Several potential operating signals originating from chloroplasts have been …

Abstract Hydrogen peroxide (H 2 O 2) acts as a signaling messenger by oxidatively
modifying distinct cysteinyl thiols in distinct target proteins. However, it remains unclear how …

Despite its very low level in humans, selenium plays an important and unique role among
the (semi) metal trace essential elements because it is the only one for which incorporation …

Abstract Dietary selenium (] Se), mainly through its incorporation into selenoproteins, plays
an important role in inflammation and immunity. Adequate levels of Se are important for …

Hydrogen peroxide (H2O2) is steadily gaining more attention in the field of molecular
biology research. It is a major REDOX (reduction–oxidation reaction) metabolite and at high …

Maintenance of the cellular redox balance is crucial for cell survival. An increase in reactive
oxygen, nitrogen, or chlorine species can lead to oxidative stress conditions, potentially …
