Abstract Glutathione (γ-glu-cys-gly; GSH) is usually present at high concentrations in most
living cells, being the major reservoir of non-protein reduced sulfur. Because of its unique …

Glutathione-deficient mutants (gshA) of the yeast Saccharomyces cerevisiae, impaired in the
first step of glutathione (GSH) biosynthesis were studied with respect to the regulation of …

Plant sulfur metabolism is deeply affected by cadmium (Cd) stress, mainly as a
consequence of the activation of a wide range of adaptive responses involving glutathione …

Glutathione (L-γ-Glutamyl-L-Cysteinylglycine) appears as the major nonprotein thiol
compound in yeasts. Recent advances have shown that glutathione (GSH) seems to be …

Publisher Summary The chapter discusses the biologically relevant chemistry of glutathione
(GSH) and its occurrence in microbial cells. The GSH-related biochemical reactions and the …

One of the defense systems against toxic heavy metals in plants is to employ cysteine-rich
chelating compounds, phytochelatins, which are polymeric forms of glutathione. In the …

Sulfur assimilation and production of sulfur-containing compounds are essential biological
activities that play critical roles in many biological processes, including the role of sulfur …

Abstract Glutathione (GSH: l-γ-glutamyl-l-cysteinylglycine) is present in high concentrations
up to 10 mM in yeast cells. Its very low redox potential (E′ o=− 240 mV for thiol disulfide …

Abstract Glutathione reductase (GR, EC 1.6. 4.2) and glutathione (GSH, γ-Glu-Cys-Gly) are
important components of the cell's scavenging system for reactive oxygen compounds in …

Glutathione (GSH) is an abundant cellular thiol which has been implicated in numerous
cellular processes and in protection against stress caused by xenobiotics, carcinogens and …
