RL   Biochemistry 26:1209-1214(1987).
CC   -!- FUNCTION: Participates in various redox reactions through the
CC       reversible oxidation of its active center dithiol to a disulfide and
CC       catalyzes dithiol-disulfide exchange reactions.
CC   -!- SIMILARITY: Belongs to the thioredoxin family. {ECO:0000305}.
