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 {ECO:0000255|HAMAP-Rule:MF_01401}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + H2O + L-methionyl-[protein] =
CC [thioredoxin]-dithiol + L-methionyl-(S)-S-oxide-[protein];
CC Xref=Rhea:RHEA:14217, Rhea:RHEA-COMP:10698, Rhea:RHEA-COMP:10700,

CC Rule:MF_01401};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + H2O + L-methionine = [thioredoxin]-
CC dithiol + L-methionine (S)-S-oxide; Xref=Rhea:RHEA:19993, Rhea:RHEA-
CC COMP:10698, Rhea:RHEA-COMP:10700, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:29950, ChEBI:CHEBI:50058, ChEBI:CHEBI:57844,
CC ChEBI:CHEBI:58772; EC=1.8.4.11; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01401};
CC -!- SIMILARITY: Belongs to the MsrA Met sulfoxide reductase family.
CC {ECO:0000255|HAMAP-Rule:MF_01401}.
