Protein Name:
Peptide methionine sulfoxide reductase A4, chloroplastic
|
UniprotKB/SwissProt ID: P54150 (P54150)
Gene Name:
MSR4
Organism: Arabidopsis thaliana (Mouse-ear cress)
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. Prevents the methionine sulfoxidation of the heat shock protein HSP21 and its subsequent inactivation. MSRA family specifically reduces the MetSO S-enantiomer
