CC   -!- FUNCTION: Has an important function as a repair enzyme for proteins
CC       that have been inactivated by oxidation. Catalyzes the reversible
CC       oxidation-reduction of methionine sulfoxide in proteins to methionine
CC       (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[thioredoxin]-disulfide + H2O + L-methionyl-[protein] =
CC         [thioredoxin]-dithiol + L-methionyl-(S)-S-oxide-[protein];
