title: Mapping of chromosomal IS5 elements that mediate type II F-prime plasmid excision in Escherichia coli K-12.
abstract: Three IS5 elements were mapped in overlapping chromosomal segments on a series of F-prime plasmids by restriction analysis and hybridization. IS5A was located clockwise of proA near 6 min, IS5B was located clockwise of purE near 12 min, and IS5C was tentatively located near 14 min on the Escherichia coli K-12 map. The physical structures of nine type II F-prime plasmids that contain chromosomal DNA from this region indicated that these plasmids were excised from the chromosome by recombination between pairs of IS5 elements.
