一般描述
Recombinant, yeast thioredoxin reductase expressed inE. coli. Yeast thioredoxin reductase is a flavoprotein that has no selenocysteine (SeCys). It catalyzes the NADPH-dependent reduction of thioredoxin as well as other endogenous and exogenous proteins. Plays an important role in many aspects of cell function, including protection against oxidative stress/injury, cell growth and transformation, and the recycling of ascorbate from its oxidized form.
