Protein Name:
Peptide methionine sulfoxide reductase B2, chloroplastic
|
UniprotKB/SwissProt ID: Q9C5C8 (Q9C5C8)
Gene Name:
MSRB2
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Catalyzes the reduction of methionine sulfoxide (MetSO) to methionine in proteins. Specifically reduces the MetSO R-enantiomer. Plays a protective role against oxidative stress by restoring activity to proteins that have been inactivated by methionine oxidation. May play an essential function in association with MSRB1 in maintaining vegetative growth during environmental constraints, through the preservation of photosynthetic antennae. MSRB1 and MSRB2 account for most of the leaf peptide MSR capacity
