DE   Peptide-methionine (S)-S-oxide reductase.
AN   Methionine S-oxide reductase.
AN   Methionine S-oxide reductase (S-form oxidizing).
AN   Methionine sulfoxide reductase.
AN   Methionine sulfoxide reductase A.
AN   Methionine sulphoxide reductase A.
AN   Peptide Met(O) reductase.
AN   Peptide methionine sulfoxide reductase.
CA   (1) Peptide-L-methionine + thioredoxin disulfide + H(2)O = peptide-L-
CA   methionine (S)-S-oxide + thioredoxin.
CA   (2) L-methionine + thioredoxin disulfide + H(2)O = L-methionine (S)-S-
CA   oxide + thioredoxin.
CC   -!- The reaction occurs in the reverse direction to that shown above.
CC   -!- Exhibits high specificity for the reduction of the S-form of
CC       L-methionine S-oxide, acting faster on the residue in a peptide than
CC       on the free amino acid.
CC   -!- On the free amino acid, it can also reduce D-methionine (S)-S-oxide
CC       but more slowly.
CC   -!- Plays a role in preventing oxidative-stress damage caused by reactive
CC       oxygen species by reducing the oxidized form of methionine back to
CC       methionine and thereby reactivating peptides that had been damaged.
CC   -!- The reaction proceeds via a sulfenic-acid intermediate.
CC   -!- Formerly EC 1.8.4.6.
