CC ChEBI:CHEBI:50058; EC=1.8.4.12; Evidence={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.
