thioredoxin reductase

thi·o·re·dox·in re·duc·tase

a flavoprotein that uses NADPH to re-reduce thioredoxin in the formation of deoxyribonucleotides.

PRDX5

A gene on chromosome 11q13 that encodes peroxiredoxin 5, which is involved in intracellular redox signalling. It reduces hydrogen peroxide and alkyl hydroperoxides with reducing equivalents provided in the thioredoxin system.
