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.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an alkylmercury + H(+) = an alkane + Hg(2+);

CC         ChEBI:CHEBI:18310, ChEBI:CHEBI:83725; EC=4.99.1.2;
CC   -!- SIMILARITY: Belongs to the MerB family. {ECO:0000305}.
