RA   Partridge S.R., Hall R.M.;
RT   "A complex multi-drug and mercury resistance region derived from a Tn2670-
RT   like transposon.";
RL   Submitted (JAN-2004) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Cleaves the carbon-mercury bond of organomercurials such as
CC       phenylmercuric acetate. One product is Hg(2+), which is subsequently
CC       detoxified by the mercuric reductase. {ECO:0000255|HAMAP-
CC       Rule:MF_00714}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an alkylmercury + H(+) = an alkane + Hg(2+);
CC         Xref=Rhea:RHEA:18777, ChEBI:CHEBI:15378, ChEBI:CHEBI:16793,
CC         ChEBI:CHEBI:18310, ChEBI:CHEBI:83725; EC=4.99.1.2;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00714};
CC   -!- SIMILARITY: Belongs to the MerB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00714}.
