General annotation (Comments)

Function	Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine By similarity. HAMAP MF_01401
Catalytic activity	Peptide-L-methionine + thioredoxin disulfide + H2O = peptide-L-methionine (S)-S-oxide + thioredoxin. HAMAP MF_01401 L-methionine + thioredoxin disulfide + H2O = L-methionine (S)-S-oxide + thioredoxin. HAMAP MF_01401
Sequence similarities	Belongs to the msrA Met sulfoxide reductase family.
