DNA supercoiling in gyrase mutants.
Nucleoids isolated from Escherichia coli strains carrying temperature-sensitive gyrA or gyrB mutations were examined by sedimentation in ethidium bromide-containing sucrose density gradients. A shift to restrictive temperature resulted in nucleoid DNA relaxation in all of the mutant strains. Three o...
