title: The Clostridium perfringens chloramphenicol resistance transposon Tn4451 excises precisely in Escherichia coli.
abstract: Nucleotide sequence analysis of the Tn4451-deletion derivatives, pJIR47 and pJIR86, which were derived from Escherichia coli and Clostridium perfringens, respectively, showed that the deletion events that led to the formation of these plasmids were identical and precise. The results also showed that the termini of this C. perfringens-derived transposon contained imperfect 12-bp inverted repeat sequences which had some sequence similarity with the termini of Tn3-like transposons.
