The DNA unwinding element: a novel, cis-acting component that facilitates opening of the Escherichia coli replication origin.
We have discovered that DNA supercoiling, in the absence of replication proteins, induces localized unwinding in the Escherichia coli replication origin (oriC) at the same sequence opened by the dnaA initiator protein. The DNA helix at the tandemly repeated, 13mer sequence is thermodynamically unsta...
