title: [Isolation of transmissible cointegrates of Yersinia pestis plasmids pYV and pYT with the plasmid RP4::Mu cts 62, IncP1].
abstract: The transmissible cointegrates of the Yersinia pestis plasmids pYV and pYT with the broad host range plasmid RP4::Mu cts62 of the incompatibility group IncP have been constructed by the in vivo recombination. The cointegrative plasmid pKR14 (pYV76 omega RP4::Mu cts62) conferred on the transconjugants the properties of Ca2(+)-dependence at 37 degrees C, V-antigen synthesis, RP4 plasmid markers (ApR, KmR, TcR), immunity to the lysis by the bacteriophage Mu cts62 and incompatibility with the homologous replicon pYV76. Cointegrates pKR103 and pKR106 (pYT omega RP4::Mu cts62) conferred on the transconjugant clones the ability to synthesize the "mouse" toxin and fraction I. The capability of Escherichia coli cells to synthesize the latter products has been demonstrated together with the deficiency of these cells to transport the synthesized fraction I to the cell surface.
