Plasma membrane gamma-glutamyltransferase activity facilitates the uptake of vitamin C in melanoma cells. [PDF]
, 2004 Adequate cellular transport of ascorbic acid (AA) and its oxidation product dehydroascorbate (DHA) is assured through specific carriers. It was shown that vitamin C is taken up as DHA by most cell types, including cancer cells, via the facilitative ...

The Antioxidants of Legume Nodule Mitochondria
Molecular Plant-Microbe Interactions, 2001 The mitochondria of legume root nodules are critical to sustain the energy-intensive process of nitrogen fixation. They also generate reactive oxygen species at high rates and thus require the protection of antioxidant enzymes and metabolites.

Journal of Nutritional Science and Vitaminology, 2006 We constructed an expression vector for rice dehydroascorbate reductase (DHAR) (EC 1.8.5.4) with a polyhistidine tag at the amino terminus and introduced the vector into several strains of Escherichia coli. On conventional induction treatment with isopropylthiol-beta-D-galactoside, E. coli harboring rice DHAR cDNA produced doublet polypeptides of about

Cytosolic Dehydroascorbate Reductase is Important for Ozone Tolerance in Arabidopsisthaliana [PDF]
Plant and Cell Physiology, 2006 Dehydroascorbate reductase (DHAR) is a key component of the ascorbate recycling system. Three functional DHAR genes are encoded in the Arabidopsis genome. Ozone exposure increased the expression of the cytosolic DHAR (cytDHAR) gene alone. We characterized an Arabidopsis mutant with a deficient cytDHAR.

Antioxidants, 2023 Allantoin is an emerging plant metabolite, but its role in conferring drought-induced oxidative stress is still elusive. Therefore, an experiment was devised to explore the role of allantoin (0.5 and 1.0 mM; foliar spray) in rapeseed (Brassica campestris
