CC -!- FUNCTION: Catalyzes the reduction of methionine sulfoxide (MetSO) to
CC methionine in proteins. Plays a protective role against oxidative
CC stress by restoring activity to proteins that have been inactivated by
CC methionine oxidation. MSRB family specifically reduces the MetSO R-
CC enantiomer (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + H2O + L-methionyl-[protein] =
CC [thioredoxin]-dithiol + L-methionyl-(R)-S-oxide-[protein];
CC Xref=Rhea:RHEA:24164, Rhea:RHEA-COMP:10698, Rhea:RHEA-COMP:10700,

CC ChEBI:CHEBI:50058; EC=1.8.4.12;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the MsrB Met sulfoxide reductase family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAD03449.1; Type=Erroneous gene model prediction; Note=The predicted gene has been split into 2 genes: At4g04800 and At4g04810.; Evidence={ECO:0000305};
