[Molecular genetic organization and origin of plasmid pBS52 with a broad range of bacterial hosts].
The data are presented on the localization of genetic determinants of resistance to streptomycin, ampicillin and sulfanilamides on the physical map of conjugative R plasmid pBS52 of 38,000 bp which has a broad bacterial host range and belongs to a new incompatibility group. The plasmid has a natural "polylinker" site (less than 200 bp) containing (in the order of arrangement) the recognition sites for restriction enzymes: BamHI-EcoRI-PstI-EcoRV-BglII (PvuII). The comparative analysis shows that pBS52 contains a segment homologous to DNA of plasmid RSE1010 (IncP-4). The evolutionary origin of plasmid pBS52 is discussed. The recA-independent formation of the mini-derivatives of pBS373 and pBS374 types during the transformation of Escherichia coli with pBS52 plasmid DNA has been shown. Plasmids pBS373 and yBS374 are capable of autonomous replication in Pseudomonas putida and P. aeruginosa cells, which is provided by the rep system of IncP-4 replicon.
