DnaD is a primosomal protein that remodels supercoiled plasmids. It binds to supercoiled forms and converts them to open forms without nicking. The DnaD N-terminal domain has a scaffold-forming activity. This domain adopts classical winged helix fold decorated with extensions at both termini [1-2].	Domain
