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 COMP:10698, Rhea:RHEA-COMP:10700, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:29950, ChEBI:CHEBI:50058, ChEBI:CHEBI:57844,
CC ChEBI:CHEBI:58773; EC=1.8.4.14;
CC Evidence={ECO:0000256|ARBA:ARBA00000502};
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}.
