Identification of S-glutathionylated cellular proteins during oxidative stress and constitutive metabolism by affinity purification and proteomic analysis.
Redox modification of proteins is proposed to play a central role in regulating cellular function. However, high-throughput techniques for the analysis of the redox status of individual proteins inExpand
DT-diaphorase as a quinone reductase: a cellular control device against semiquinone and superoxide radical formation.
Abstract Rat liver microsomes incubated in the presence of NADPH catalyze the oxidation of menadione (2-methyl-1,4-naphthoquinone) by two pathways: NADPH-cytochrome P-450 reductase and DT-diaphorase.Expand
Studies on the mechanism of oxidative modification of human glyceraldehyde-3-phosphate dehydrogenase by glutathione: catalysis by glutaredoxin.
In this report the protein human glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been examined to clarify the roles of (a) direct oxidation and (b) thiol-disulphide exchange (with glutathioneExpand
[30] DT-diaphorase : purification, properties, and function
Publisher Summary DT-diaphorase is a highly active diaphorase in the soluble fraction of rat liver homogenates, which catalyzes the oxidation of nicotine adenine dinucleotide, reduced nicotineExpand
S-glutathionylation of glyceraldehyde-3-phosphate dehydrogenase: role of thiol oxidation and catalysis by glutaredoxin.
The findings in this article illustrate the complexity residing in the regulation of reversible S-glutathionylation of proteins, such as GAPDH. This is clearly reflected in the design of suitableExpand
On the mechanism of the Mn3(+)-induced neurotoxicity of dopamine:prevention of quinone-derived oxygen toxicity by DT diaphorase and superoxide dismutase.
Dopamine (DA) is rapidly oxidized by Mn3(+)-pyrophosphate to its cyclized o-quinone (cDAoQ), a reaction which can be prevented by NADH, reduced glutathione (GSH) or ascorbic acid. The oxidation of DAExpand
Determination of intracellular glutathione in human skeletal muscle by reversed-phase high-performance liquid chromatography.
A chromatographic method for the specific determination of cellular low molecular mass thiols has been applied to human muscle tissue. The method is based on the derivatisation of thiols usingExpand
Determination of site-specificity of S-glutathionylated cellular proteins.
Redox modification by S-glutathionylation is an expanding field within cell signalling research. However, the methods available for analysis of S-glutathionylated proteins in complex mixtures are notExpand
Biospecific adsorption of hepatic DT-diaphorase on immobilized dicoumarol. II. Purification of mitochondrial and microsomal DT-diaphorase from 3-methylcholanthrene-treated rats.
Abstract Liver mitochondrial and microsomal DT-diaphorase have been purified from 3-methylcholanthrene-treated rats. A 1150-fold and 3500-fold purification of mitochondrial and microsomalExpand
