Characterization of the monomethylarsonate reductase and dehydroascorbate reductase activities of Omega class glutathione transferase variants: implications for arsenic metabolism and the age-at-onset of Alzheimers and Parkinsons diseases

, 2015
There are two functional Omega class glutathione transferase (GST) genes in humans. GSTO1 is polymorphic with several coding region alleles, including an A140D substitution, a potential deletion of E155 and an E208K substitution.

The proposed AsA synthetic and recycling pathways in higher plants.

, 2016
The four pathway included GalUA (D-galacturonic acid) pathway, Gal (L-galactose) pathway, Gulose(L-gulose) pathway and MI (Myo-inositol) pathway which catalyzed by GUR (D-galacturonate reductase), GME (GDP–D–Mannose-3,5-epimerase), GGP (GDP-L-galactose ...

Low-intensity light stress on broccoli seedlings: associated mechanisms of acclamatory stress tolerance through changes in pigments, membrane lipids, and amelioration of antioxidative defense systems [PDF]

Brazilian Journal of Biology
Low-intensity light (LL; 100 µmol m–2 s–1PPFD) effects on growth and biochemical parameters indicative of acclimation were investigated on 21-day-old broccoli seedlings. LL stress reduces the biomass and thickness of the leaf.

Cloning, Expression, and Characterization of an Enzyme Possessing both Glutaredoxin and Dehydroascorbate Reductase Activity from Taiwanofungus Camphorata

, 2013
[[abstract]]Glutaredoxins (Grxs) play important roles in the reduction of disulfides via reduced glutathione as a reductant. A cDNA (503 bp, EU193660) encoding a putative Grx was cloned from Taiwanofugus camphorata (Tc).

Molecular analysis of monodehydroascorbate reductase and dehydroascorbate reductase in plants

, 2000
Oxidative stress is an inevitable phenomenon in green plants because they generate toxic reactive oxygen species. Through normal metabolism plants produce copious amount of molecular oxygen in cellular organelles that carry out highly energetic electron ...

Purification of NADPH-dependent dehydroascorbate reductase from rat liver and its identification

, 1994
Rat liver cytosol has been found to reduce dehydroascorbic acid (DHAA) to ascorbic acid in the presence of NADPH. The enzyme responsible for such activity has been purified by ammonium sulphate fractionation, DEAE-Sepharose, Sephadex G-100 SF and ...

Immunohistochemical evidence and ultrastructural compartmentalization of a new antioxidant enzyme in the rat substantia nigra

, 2001
We previously described in the rat the presence of dehydroascorbate reductase, an enzyme regenerating ascorbic acid, which is constantly lost during oxidative processes occurring at a fast rate within the central nervous system.

Biochemical characterization of transgenic tobacco plants expressing a human dehydroascorbate reductase gene

, 2001
Dehydroascorbate (DHA) reductase (DHAR, EC 1.8.5.1) catalyzes the reduction of DHA to reduced ascorbate (AsA) using glutathione (GSH) as the electron donor in order to maintain an appropriate level of ascorbate in plant cells.
