Abstract

We report the complete sequence of a transposon found in a cosmid clone of a human DNA sequence. The transposon is identified as the Escherichia coli transposon Tn1000 (also known as gamma delta) on the basis of the identity of the restriction map of the new sequence with that previously recorded for Tn1000 and homology between parts of the new sequence and that of published fragments of Tn1000 sequence. The transposon, which comprises 5,981 nucleotides including two 35 bp inverted terminal repeat sequences (ITRs), contains three open reading frames. The sequence of the resolvase coding region (tnpR) is identical to that published by others. A second reading frame can be identified as the tnpA gene, coding for the transposase, on the grounds of its strong homology with the corresponding gene from transposon Tn3. The third reading frame has the potential to code for a protein of unknown function containing 698 amino acids.
