Abstract:
:We present the complete nucleotide sequence of a mer operon located on a 60-kb conjugative plasmid pKLH2 from an environmental bacterium, Acinetobacter calcoaceticus, isolated from a mercury mine. The pKLH2 mer operon has essentially the same gene organization as that of Tn21 and Tn501 from clinical bacteria. The pKLH2 mer operon nucleotide sequence shows 85.5% identity with the Tn501 and 80.9% identity with the Tn21 sequences. Vestigial sequences have been found at the ends of the pKLH2 mer operon, indicating that the pKLH2 mer operon was once a part of a Tn21-like transposon, which had committed suicide by an aberrant resolution event.
