Stabilization of the cloning vector pACYC184 by insertion of F plasmid leading region sequences.
The leading region of the F plasmid is, by definition, the first part of the plasmid DNA to be transferred to the recipient cell during conjugation. Restriction fragments of the leading region, when cloned into the plasmid vector pACYC184, extended the maintenance of the normally unstable p15A-derived vector replicon in rec+ Escherichia coli K-12 cells. Mutations in the host's general recombination systems were found to influence the maintenance of these hybrid plasmids.
