Replication of ColE1 plasmid deoxyribonucleic acid in a thermosensitive dnaA mutant of Escherichia coli.
J Bacteriol. 1980 Mar; 141(3):1024-30.JB

Abstract

The replication of ColE1 deoxyribonucleic acid (DNA) took place at the restrictive temperature in a dnaA mutant, dnaA167(Ts). It proceeded at a constant rate at 42 degrees C for at least 3 h. The replication was insensitive to rifampin, which blocked replication at the permissive temperature or in the presence of chloramphenicol, even at the restrictive temperature. A linear DNA strand of ColE1 longer than unit genome size was synthesized. The structure of the replicating molecules observed by electron microscopy was mostly sigma shaped, composed of a circle of a unit genome length with a double-stranded tail. These observations suggest that the replication of ColE1 DNA proceeds via a rolling-circle type of structure in the absence of dnaA function.
