Isolation and characteristics of a recombinant pOV13 plasmid as a vector for DNA cloning in a broad range of bacterial hosts

The hybrid plasmid pOV13 proposed as a potential vector for DNA cloning in a broad bacterial host range has been constructed on the basis of the broad host range plasmid RSF1010 and a shortened derivative of RP4, the plasmid pVZ115 serving a marker DNA fragment. The plasmid pOV13 contains the genes for streptomycin, kanamycin and tetracycline resistance and single cleavage sites for restriction endonucleases BamHI, BgIII, SalI, SmaI, PvuII, XhoI, as well as double cleavage sites for restriction endonucleases PstI and HindIII permitting one to clone DNA with insertional inactivation of genes. The physicogenetical map of the birepliconed plasmid pOV13 is presented.
