abstract：:The plasmids R1162 and pSC101 have origins of conjugative transfer (oriTs) and corresponding relaxases that are closely related. The oriTs are made up of a highly conserved core, where DNA is cleaved by the relaxase prior to transfer, and an inverted repeat that differs in size and sequence. We show that in each case ...
