Complete nucleotide sequence of Tn10

The complete nucleotide sequence of Tn10 has been determined. The dinucleotide signature and percent G+C of the sequence had no discontinuities, indicating that Tn10 constitutes a homogeneous unit. The new sequence contained three new open reading frames corresponding to a glutamate permease, repressors of heavy metal resistance operons, and a hypothetical protein in Bacillus subtilis. The glutamate permease was fully functional when expressed, but Tn10 did not protect Escherichia coli from the toxic effects of various metals.
