Isoform 1: Mitochondrion.; Isoform 2: Cytoplasm.; Isoform 3: Cytoplasm. Nucleus.; Isoform 5: Cytoplasm. Membrane

Function

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.
Catalytic Activity:
Peptide-L-methionine + thioredoxin disulfide + H(2)O = peptide-L-methionine (S)-S-oxide + thioredoxin.; L-methionine + thioredoxin disulfide + H(2)O = L-methionine (S)-S-oxide + thioredoxin.
