We have used purified RSF1010 mobilization proteins to reproduce in vitro a strand-specific nicking at the plasmid origin of transfer, oriT. In the presence of Mg2+, the proteins MobA (78-kDa form of RSF1010 DNA primase), MobB, and MobC and supercoiled or linear duplex oriT DNA form large amounts of a cleavage complex, which is characterized by its(More)
