Glutathione reductase and thioredoxin reductase at the crossroad: The structure of Schistosoma mansoni thioredoxin glutathione reductase

Proteins: Structure, Function, and Bioinformatics, 2008
AbstractThioredoxin glutathione reductase (TGR) is a key flavoenzyme expressed by schistosomes that bridges two detoxification pathways crucial for the parasite survival in the host's organism. In this article we report the crystal structure (at 2.2 Å resolution) of TGR from Schistosoma mansoni (SmTGR), deleted in the last two residues.

Gene duplication in glutathione reductase

Journal of Molecular Biology, 1980
Abstract The two nucleotide-binding domains of the flavo-enzyme glutathione reductase have similar chain folds. In order to evaluate whether the observed similarity is significant or not, a mean distance between both chains after best overlay was calculated. Insertions and deletions were taken into account. The significance of the observed similarity

Glutathione reductase from Rhodospirillum rubrum

Archiv f�r Mikrobiologie, 1969
Glutathione reductase (NADPH1: glutathione oxidoreductase (EC 1.6.4.2) was purified 70 fold from Rhodospirillum rubrum by ammonium sulfate fractionation, gelfiltration with Sephadex and chromatography on DEAE-cellulose. The optimum pH of the reaction is 7.5–8.2 Kmvalues of 8.4×10−6 M for NADPH and 5.8×10−5 M for GSSG were determined.

Measurement of Glutathione Reductase Activity

Current Protocols in Toxicology, 1999
AbstractReduced glutathione, a thiol, is essential to the survival of the cells of most aerobic organisms. It is present intracellularly and provides protection from hydroperoxides and free radicals. This unit describes a continuous spectrophotometric assay for reductase activity: it follows the reduction of glutathione disulfide to reduced glutathione

Elemental selenium and glutathione reductase

Medical Hypotheses, 1985
Selenium is an essential trace element important to several metabolic processes, although selenium in the chemical form of elemental selenium (Se degree) is commonly believed to be biologically inert. Recent data shows that colloidal suspensions of red amorphous elemental selenium are more easily reduced than previously thought, and that such ...

[202] Glutathione reductase (Yeast)

1971
Publisher Summary This chapter discusses the methods of preparation of Glutathione Reductase (Yeast). Enzymatic activity is measured spectrophotometrically by observing the rate of decrease in absorbance of TPNH at 340 mμ. One unit of enzyme is defined as that amount of enzyme which catalyzes the oxidation of 1 micromole of TPNH per minute at 25 ...
