Abstract

Transposition of mini-Mu containing only one of the ends of bacteriophage Mu was studied. Transposition was observed when plasmids containing this mini-Mu were used as the donor in a mating-out assay with the F factor POX38, which lacks all known transposable elements, as the target. Analysis of the plasmids isolated from the recipient strain showed that in most cases the mini-Mu containing plasmid and POX38 were fused and that a part of the plasmid had been duplicated, indicating the formation of co-integrates. To obtain the DNA sequences of the junctions between donor and recipient DNA, an F factor was constructed that made it possible to analyse these junctions directly. The results showed that several sequences can be used as an alternative end in transposition and that these alternative ends show homology with the consensus for a strong A binding site. Moreover, the first base pair at the junction was always a (TA) base pair. This base pair is situated at exactly the same position with respect to the sequence which has homology with the consensus for a strong A binding site as in the ends of Mu.
