Molecular Cloning and Functional Expression of Rat Liver Glutathione-dependent Dehydroascorbate Reductase [PDF]

Journal of Biological Chemistry, 1998
We have isolated a cDNA clone for a novel glutathione-dependent dehydroascorbate reductase from a rat liver cDNA library in lambdagt11 by immunoscreening. The authenticity of the clone was confirmed as follows: first, the antibody that had been purified through affinity for the protein expressed by the cloned lambdagt11 phage recognized only the enzyme

Identification and Analysis of Proteins Sharing Dehydroascorbate Reductase Activity [PDF]

Biologia plantarum, 2002
Dehydroascorbate (DHA)-reducing proteins were observed using a native-PAGE/activity staining method, and identified in soybean and rice by Western analysis using antibodies against homologous protein known to catalyse DHA reduction. Administration of 1 mM DHA apparently did not trigger DHA reductase activity in lupin and onion, whereas activity was ...

Impact of cadmium and hydrogen peroxide on ascorbate-glutathione recycling enzymes in barley root

Plant, Soil and Environment, 2013
We analyse the effect of Cd and H2O2 short-term treatments on the activity of ascorbate-glutathione recycling enzymes in barley root tip. Even a short transient exposure of barley roots to low 15 µmol Cd concentration caused a marked approximately 70 ...

Ascorbate peroxidase plays an important role in photoacclimation in the extremophilic red alga Cyanidiococcus yangmingshanensis

Frontiers in Plant Science, 2023
IntroductionAcidothermophilic cyanidiophytes in natural habitats can survive under a wide variety of light regimes, and the exploration and elucidation of their long-term photoacclimation mechanisms promises great potential for further biotechnological ...

Effects of lanthanum on the antioxidant capacity of chloroplasts and chlorophyll fluorescence parameters of maize seedlings under chromium stress

Photosynthetica, 2019
Effects of lanthanum chloride (LaCl3) on chromium tolerance of maize were investigated at chloroplast level. The results showed that Cr stress significantly increased activities of ascorbate peroxidase, glutathione reductase, monodehydro-ascorbate ...

Supplemental Ascorbate Diminishes DNA Damage Yet Depletes Glutathione and Increases Acute Liver Failure in a Mouse Model of Hepatic Antioxidant System Disruption

Antioxidants, 2021
Cellular oxidants are primarily managed by the thioredoxin reductase-1 (TrxR1)- and glutathione reductase (Gsr)-driven antioxidant systems. In mice having hepatocyte-specific co-disruption of TrxR1 and Gsr (TrxR1/Gsr-null livers), methionine catabolism ...

Effects of lanthanum on the ascorbate and glutathione metabolism of Vigna radiata seedlings under salt stress

Biologia Plantarum, 2014
In order to elucidate the role of lanthanum (La) in response of Vigna radiata to a salt stress, we investigated the effects of La on the ascorbate and glutathione metabolism.
