Title Clustering of genes involved in replication, copy number control, incompatibility, and stable maintenance of the resistance plasmid R1drd-19.
Journal J Bacteriol
Abstract Plasmid R1drd-19 is present in a small number of copies per cell of Escherichia coli. The plasmid was reduced in size by in vivo as well as in vitro (cloning) techniques, resulting in a series of plasmid derivatives of different molecular weight. All plasmids isolated contain a small region (about 2 x 10(6) daltons of deoxyribonucleic acid) of the resistance transfer factor part of the plasmid located close to one of the IS1 sequences that separates the resistance transfer factor part from the resistance determinant. All these derivatives were present at the same copy number, retained the incompatibility properties of plasmid R1drd-19, and were stably maintained during cell division. Genes mutated to yield copy mutations also were found to be located in the same region.
