Protein
Peptide methionine sulfoxide reductase B8
Organism
Arabidopsis thaliana
Function
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. MSRB family specifically reduces the MetSO R-enantiomer (By similarity).
Similarity
Belongs to the MsrB Met sulfoxide reductase family.
