Abstract
Supercoiled minicircular deoxyribonucleic acid (DNA) molecules with molecular weights of 1.8 × 10
6
and 2.3 × 10
6
have been isolated from two wild strains of
Escherichia coli
. DNA-DNA hybridization experiments indicate that these DNA molecules share extended homologies with the minicircular DNA of
E. coli
15. The DNA of the colicinogenic factor E1 (ColE1) also hybridizes to a large extent with minicircular DNA of
E. coli
15. In contrast, no hybridization could be detected with various large extrachromosomal DNA elements such as the colicinogenic factor V (ColV), the beta-hemolytic factor (Hly), or the P1-like DNA of
E. coli
15. Two different insertion DNA species of
E. coli
integrated into λdg-DNA (λdg UP
in
128, λdg UP
in
308) do not show any annealing with minicircular DNA of
E. coli
15.
