AFM imaging of DnaD complexes with closed circular and linear DNAs. (a) Complexes of DnaD with supercoiled pBR322. Free supercoiled pBR322 plasmids on the left and DnaD-pBR322 complexes on the right. DnaD converts the supercoiled plasmid into an open circular form as observed.12 The scale bars represent 100 nm. (b) Complexes of DnaD with linear λ dsDNA. Afree λ dsDNA molecule on the left and DnaD-λ dsDNA complexes on the right. DnaD converts the linear DNA into a circular form. A partially circularised λ dsDNA molecule bound to DnaD is also shown (bottom right). The scale bar in the right panel represents 100 nm.
