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).
CATALYTIC ACTIVITY: Peptide-L-methionine + thioredoxin disulfide + H₂O = peptide-L-methionine (S)-S-oxide + thioredoxin.
CATALYTIC ACTIVITY: L-methionine + thioredoxin disulfide + H₂O = L-methionine (S)-S-oxide + thioredoxin.
SIMILARITY: Belongs to the msrA Met sulfoxide reductase family.
