thioredoxin | rat-reduced thioredoxin activates the enzyme 2.3fold after treatment with dithiothreitol, but dithiothreitol does not increase enzyme activity. The Escherichia coli thioredoxin-thioredoxin reductase-NADPH system more effectively increases enzyme activity to 4.5fold that of the control than the rat thioredoxin-thioredoxin reductase-NADPH system, which increases enzyme activity to 3fold that of the control | Mus musculus | |

tetrathionate | reduced GSH and GSH together with the reducing system partially restore the activity of tetrathionate-inhibited enzyme. Enzyme that is oxidized by an excess molar dose of tetrathionate is completely reactivated by dithiothreitol, reduced thioredoxin, and thioredoxin together with the reducing system | Mus musculus | |
