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 Rhea:RHEA-COMP:12313, Rhea:RHEA-COMP:12314, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:16044, ChEBI:CHEBI:29950, ChEBI:CHEBI:45764,
CC ChEBI:CHEBI:50058; EC=1.8.4.12;
CC Evidence={ECO:0000256|ARBA:ARBA00001795, ECO:0000256|HAMAP-
CC Rule:MF_01400};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01400};
CC Note=Binds 1 zinc ion per subunit. The zinc ion is important for the
CC structural integrity of the protein. {ECO:0000256|HAMAP-Rule:MF_01400};
CC -!- SIMILARITY: Belongs to the MsrB Met sulfoxide reductase family.
CC {ECO:0000256|HAMAP-Rule:MF_01400}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
