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
- [thioredoxin]-disulfide + L-methionine + H2O = L-methionine (S)-S-oxide + [thioredoxin]-dithiol
