In the version of this News and Views initially published, the authors present a model to explain the low degree of positive DNA supercoiling generated during DNA translocation through the FtsK helicase. The authors' conclusion, that in a rotary inchworm model for DNA translocation the helicase should generate positive supercoils ahead of itself when taking steps of less than 1.7 base pairs, is incorrect. Positive supercoils should be generated by steps of more than 1.7 base pairs, as described by Massey et al. (Mol. Cell 23, 457–469, 2006) and as pointed out to the authors by Dr. Ian Grainge. The authors deeply regret this error and apologize for any misunderstandings it may have caused.
