Sequence and analysis of a plasmid-encoded mercury resistance operon from Mycobacterium marinum identifies MerH, a new mercuric ion transporter.

ABSTRACT: In this study, we report the DNA sequence and biological analysis of a mycobacterial mercury resistance operon encoding a novel Hg(2+) transporter. MerH was found to transport mercuric ions in Escherichia coli via a pair of essential cysteine residues but only when coexpressed with the mercuric reductase.
