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. {ECO:0000250}.
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the thioredoxin family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAN45291.2; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
CC Sequence=AAP18906.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
