pUC18R6KT-miniTn7BB-Gm-tetR

pUC18R6KT-miniTn7BB-Gm-tetR is a vehicle vector for the minitransposon miniTn7BB-Gm-tetR. This transposon is a part of the [http://2011.igem.org/Team:UPO-Sevilla/Foundational_Advances/MiniTn7/Overview miniTn7 BioBrick toolkit], a set of plasmids harboring Tn7 derivatives that can be used for integration of BioBricks in single copy at a conserved target (the attTn7 site), in multiple bacterial genomes.

The mini-Tn7-Gm-tetR artificial transposon has been constructed based on pUC18R6KT-miniTn7-Gm (BBa_K510012) by inserting a tetR/ptetR cassette (BBa_I732083) in its BioBrick cloning site (BCS). This plasmid can be used as inducible expression system in single copy by integrating the device in the genome of the working organism.

The structure of the mini-Tn7BB-Gm-tetR transposon is shown in the figure below. Tn7R and Tn7L are the right and left ends of Tn7 transposon, respectively, required for recognition of the transposase machinery and transposition. FRT is the Flp recombinase target site for excision of the resistance once the transposon is inserted in the genome of a living organism. The gentamycin resistance cassette (Gm) is flanked by restriction sites in order to facilitate the generation of variants with different antibiotic resistance markers. The tetR/ptetR cassette has been inserted in the BioBrick cloning site (BCS).

This plasmid is replicative only in E. coli strains expressing the pir gene thanks to its R6K replication origin. Also it has an origin for transference (oriT) for conjugation purposes. This plasmid can be used to maintain the miniTn7BB-Gm-tetR transposon in E. coli pir+ strains and may be used for transposition into the genomes of any bacteria without the pir gen, in which it is non-replicative. As a BioBrick cloning vector, pUC18R6KT-miniTn7BB-Gm-tetR is fully compatible with Assembly Standard 10. The complete transposon is flanked by SfiI restriction sites to facilitate subcloning in other vectors.
