Webinvolved in the initiation of conjugative transfer replication, we isolated and sequenced the transfer origins (oriT) of the promiscuous IncP plasmids RP4 and R751. The central initi-ating event at the transfer origin of a conjugative plasmid is the cleavage at a unique site (nic) of the strand to be transferred to a recipient cell. WebInsertional disruptions of 9 of the 14 open reading frames (ORFs) in the Tra1 region resulted in a transfer-deficient phenotype. Conjugative transfer was restored for each transfer mutant by genetic complementation. An intergenic region between traH and trhR was cloned and mobilized by R27, indicating the presence of an origin of transfer (oriT).
