TRANSLOCATIONAbstract:
In Escherichia coli, the ATP-dependent DNA translocase FtsK transports DNA across the site of cell division and activates recombination by the XerCD recombinases at a specific site on the chromosome, dif, to ensure the last stages of chromosome segregation. DNA transport by FtsK is oriented by 8-base-pair asymmetric sequences ('KOPS'). Here we provide evidence that KOPS promote FtsK loading on DNA and that translocation is oriented at this step.
