Involvement of DNA superhelicity in minichromosome maintenance in Escherichia coli.

Evidence is presented that Escherichia coli minichromosomes are harbored at superhelical densities which are lower than those measured for other E. coli plasmids but are comparable to that of the chromosome. When introduced into gyrB decreased-supercoiling mutants, minichromosomes were much more uns...
