Effects of rifampicin on the relationship of R6K replicating forms to the folded chromosomal complex of Escherichia coli

The intracellular location of plasmid DNA has been of interest in an effort to understand the maintenance of these molecules. We have employed a simple procedure which enables us to isolate from exponentially grown cells on sucrose gradients membrane-complexed forms of R6K plasmid DNA. Electron micrographs identified the complexing of membrane fractions to circular forms of R6K DNA. Biochemical studies of the complexed R6K molecules showed the presence of membrane-specific proteins and suggested that complexing of R6K DNA was primarily with inner membrane fractions of Escherichia coli.
