Potassium ions and changes in bacterial DNA supercoiling under osmotic stress
Escherichia coli transiently increases both the [ATP]/[ADP] ratio and the negative supercoiling of plasmid DNA when it is shifted to high osmolarity. Here we report that a mutant lacking all saturable K+ transport systems increases the negative supercoiling of the plasmid DNA under upshock but canno...

| description | Escherichia coli transiently increases both the [ATP]/[ADP] ratio and the negative supercoiling of plasmid DNA when it is shifted to high osmolarity. Here we report that a mutant lacking all saturable K+ transport systems increases the negative supercoiling of the plasmid DNA under upshock but cannot further relax DNA. The mutant dnaK756 behaves like the K+ transport mutant. |
