Abstract
The signature activity of condensins as DNA reshaping machines is their ability to impose the giant loop architecture onto the chromosome. At the heart of this activity lies the propensity of the proteins to assemble into macromolecular clusters that bring distant DNA segments together. This gives rise to a rich dynamic behavior when the proteins are presented with the DNA substrate. The protocols in this section describe how the interaction between Escherichia coli condensin MukB and DNA proceeds in real time as observed using magnetic tweezers.
