Mer operon, biological system found to detoxify organic and inorganic forms of mercury

converts organomercuric and cationic mercury to the less toxic volatile mercury.

Components of the mer operon

merR


merT


merP


merA


merB

The merB gene is often found immediately downstream of merA, and is essential for the detoxification and bioremediation of organic toxic mercury compounds in congruence with merA. The merB protein is a lyase that catalyzes the breaking of carbon-mercury bonds through protonolysis of toxic mercury compounds, such as methylmercury. This produces the less toxic and less mobile Hg2+ which is then completely volatilized to Hg0 when acted upon the enzyme merA. (For more information on the merB gene, see part BBa_K1420002.)
