CC   -!- CATALYTIC ACTIVITY: Thioredoxin + NADP(+) = thioredoxin disulfide
CC       + NADPH.
CC   -!- COFACTOR: Binds 1 FAD per subunit (By similarity).
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- MISCELLANEOUS: The active site is a redox-active disulfide bond.
CC   -!- SIMILARITY: Belongs to the class-II pyridine nucleotide-disulfide
CC       oxidoreductase family.
