Further information: The construction of the plasmid is described in Herrero et al. (1990).
pLOF/Km is a Tn10 based transposon vector delivery plasmid.
The transposition system consists of the IS10R transposase gene located outside the mini-Tn10 element and driven by the tac promoter, and MluI-SfiI-NotI-MluI sites between the inverted repeats of the Tn10 transposable element.
The SfiI site can be used for the cloning of foreign DNA fragments with the help of the specialized cloning vector pUC18Sfi.
The plasmid carries the kanamycin resistance gene, inserted as a NotI fragment; constructs lacking an insert between the inverted repeats do not seem to be viable.
The plasmid is unable to replicate in E. coli host strains devoid of the R6K-specified õ protein of the pir gene.
The plasmid contains the RP4 conjugal transfer origin (oriT) for transfer to a variety of Gram-negative bacteria.
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 E. coli strains expressing the tra genes of RK2/RP4 (e.g. S17-1(λpir)).
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727467.1.
The nucleotide sequence of the E. coli kanamycin-resistant Tn10-based transposon cassette corresponds with the EMBL Nucleotide Sequence Database accession number AJ601386.1.
