Further information: pKT240 is a broad-host-range plasmid. It can be used in all gram-negative bacterial species that support replication of the natural plasmid RSF1010.
pKT240 contains the structural streptomycin resistance genes (strA + strB), lacking a functional promoter, and can be used as a promoter probe vector.
Introduce the plasmid by electroporation, or through conjugation, using plasmid RK2/RP4 transfer functions (provided in trans by RK2/RP4, RK2/RP4-derived vectors, other replicons carrying RK2/RP4 transfer functions (e.g. pRK2073) or strains expressing the tra genes of RK2/RP4).
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727569.1.
The nucleotide sequence of this plasmid is based on the information in Bagdasarian et al. (1983). The intention was to ligate EcoRI-BstEII fragments of RSF1010 and pHSG415. However, the smallest EcoRI-BstEII fragment is approx. 1 kb bigger than expected. This region is indicated RSF' on the map as it contains NsiI and PstI sites, that fit with the RSF1010 sequence.
Since the nucleotide sequence could not be completely traced back, there is uncertainty as to the cutting frequency of the restriction enzymes, except for the sites that were analysed in the authenticity test.
The nucleotide sequence of RSF1010 corresponds with the EMBL Nucleotide Sequence Database accession number M28829.1.
