Although most sigma elements characterized to date are isolated insertions, a few of the elements occur relatively closely spaced. One of these pairs is a direct repeat of the sigma element separated by an internal domain 4.7 kilobase pairs in length. Not only does this structure resemble a composite transposable element, but regions within the sigma elements and intervening domain are homologous to conserved regions in retroviruses and retrotransposons of yeast and other organisms. Two features suggest that the sigma elements and intervening DNA transposed in a concerted event: only one of the two sigma elements is associated with a tRNA gene, and only the outside ends of the two elements are flanked by the 5-base pair direct repeats that usually flank individual sigma insertions. Examination of genomic DNA from five laboratory strains indicates that the 4.7 kilobase pair internal domain is present in one to four copies per haploid genome and that the genomic location of this domain differs from strain to strain. In addition, Northern blot analysis showed the presence of a 5.2 kilobase poly(A) transcript which hybridizes to both sigma and internal domain-specific probes. The existence of this composite element may suggest new ways to consider the mechanisms by which retrotransposons select their targets."xsd:string |
