UniProt Comments
Catalyzes the reduction of methionine sulfoxide (MetSO) to methionine in proteins. Plays a protective role against oxidative stress by restoring activity to proteins that have been inactivated by methionine oxidation. May prevent cellular oxidative damage due to light exposure. MSRA family specifically reduces the MetSO S-enantiomer.
