Figure 5

Dependence of dehydroascorbate reductase activity of MT-I and MT-II on GSH concentration. The reaction was carried out at 30°C by adding 100 μL MT-I and MT-II solution (100 μg protein, 100 mM phosphate buffer, pH 7.0) to 0.9 mL DHA solution with different concentrations of glutathione. The increase of absorbance at 265 nm was recorded for 5 min. Each data show the mean ± SD of one experiment performed in triplicate.
