CC -!- FUNCTION: Methionine-sulfoxide reductase that specifically reduces
CC methionine (R)-sulfoxide back to methionine. While in many cases
CC methionine oxidation is the result of random oxidation following
CC oxidative stress, methionine oxidation is also a post-translational
CC modification that takes place on specific residues.
CC {ECO:0000256|RuleBase:RU365044}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + H2O + L-methionine = [thioredoxin]-
CC dithiol + L-methionine (R)-S-oxide; Xref=Rhea:RHEA:21260, Rhea:RHEA-

CC -!- CATALYTIC ACTIVITY:
CC Reaction=[thioredoxin]-disulfide + H2O + L-methionyl-[protein] =

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.
