Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. Catalysis of the reaction: L-methionine S-oxide + thioredoxin = L-methionine + thioredoxin disulfide. Thioredoxin disulfide is the oxidized form of thioredoxin. No reaction on oxidized methionine in peptide linkage. Catalysis of the reaction: L-methionine + thioredoxin disulfide + H2O = L-methionine (R)-S-oxide + thioredoxin. Catalysis of the reaction: L-methionine + thioredoxin disulfide + H2O = L-methionine (S)-S-oxide + thioredoxin. Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces disulfide.
