Nucleotide sequence of the ends of the conjugative shuttle transposon Tn1545 (original) (raw)

Summary

The conjugative shuttle transposon Tn_1545_ from Streptococcus pneumoniae transposes in various gram-positive bacterial genera following self-transfer and in Escherichia coli after cloning. Analysis of the junction fragments and of the targets before insertion and after excision of the element by DNA hybridization and sequencing indicated that Tn_1545_ (1) is not flanked by terminal repeated sequences in either direct or opposite orientation, (2) is flanked, in an asymmetric fashion, by terminal variable base pairs, one at the left and three at the right of the element, (3) inserts in a target DNA consensus sequence, (4) does not generate duplication of the target DNA upon insertion, and (5) excises precisely.
