Abstract

The distribution of noncanonical mercury resistance transposons, Tn5044 and Tn5070 , was examined. A characteristic feature of Tn5044 is temperature sensitivity of its mercury operon and the presence in the mer operon of the gene homologous to RNA polymerase ∑ subunit. Structural organization of mercury operon Tn5070 , containing minimum gene set (merRTPA), differs from mer operons of both Gram-negative and Gram-positive bacteria. None of more than two thousand environmental bacterial strains displaying mercury resistance and isolated from the samples selected from different geographical regions hybridized to Tn5044- and Tn5070-specific probes. A concept on the existence of cosmopolite, endemic, and rare transposons in environmental bacterial populations was formulated.
