RP IDENTIFICATION.
RG EnsemblPlants;
RL Submitted (MAR-2015) to UniProtKB.
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. {ECO:0000256|RuleBase:RU365044}.
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 Evidence={ECO:0000256|RuleBase:RU365044};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|RuleBase:RU365044};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|RuleBase:RU365044};
CC -!- SIMILARITY: Belongs to the MsrB Met sulfoxide reductase family.
CC {ECO:0000256|ARBA:ARBA00007174, ECO:0000256|RuleBase:RU365044}.
