The BBa_I13521 BioBrick was inserted within the BCS of pUC18R6KT-miniTn7BB-Gm by EcoRI and PstI clonning.
The mini-Tn7-Gm-RFP artificial transposon has been constructed based on pUC18R6KT-miniTn7-Gm (BBa_K510012) by inserting a RFP cassette (BBa_I13521) in its BioBrick cloning site (BCS). This plasmid can be used for visualization purposes or to brand a strain because of its insertion in the genome of the working organism and split the antibiotic resistance cassette with the temporary expression of Flp recombinase.
The pUC18R6KT vector was amplified by PCR using as template a pTNS2 plasmid (GenBank accession number: AY884833) provided by Herbert P. Schweizer. The primers were designed to flanked the pUC18R6KT with SfiI restriction sites and allow the insertion of the mini-Tn7-Gm. Primers: attcGGCCTAGGCGGCCgtcgttttacaacgtcgtgac and attcGGCCGCCTAGGCCggaagcataaagtgtaaagcctg. The miniTn7BB-Gm minitransposon was synthesized commercially, and then digested at the flanking SfiI sites and cloned into SfiI-digested pUC18R6KT PCR products.
pUC18R6KT-miniTn7BB-Gm is a vehicle vector for the minitransposon miniTn7BB-Gm. This transposon is a part of the 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 bacteria. The structure of the mini-Tn7BB-Gm 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 BioBrick cloning site (BCS) includes the prefix and suffix restrictions sites used in assembly standard 10, and it is the place where BioBricks are inserted for genome integration. 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 miniTn7-Gm 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 is fully compatible with Assembly Standard 10. The complete transposon is flanked by SfiI restriction sites to facilitate subcloning in other vectors.

RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
Transcriptional terminator consisting of a 64 bp stem-loop.
