Abstract

Replicating circular molecules of colicin factor E1 have been isolated from minicells produced by a colicinogenic derivative of Escherichia coli P678-54. The replicating structures observed in electron micrographs are circular molecules with two branched points. Several structures found among the replicating molecules are interpretable as replicating rolling circles.
