Protein
Peptide methionine sulfoxide reductase A4, chloroplastic
Organism
Oryza sativa subsp. japonica
Function
Catalyzes the reduction of methionine sulfoxide (MetSO) to methionine in proteins. Involved in abiotic and salt stress responses. Plays a protective role against oxidative stress by restoring activity to proteins that have been inactivated by methionine oxidation. MSRA family specifically reduces the MetSO S-enantiomer.
Similarity
Belongs to the MsrA Met sulfoxide reductase family.
