Genome Integration

The parts in the miniTn7 BioBrick toolkit are based on the excellent set of miniTn7 derivatives developed by Choi et al. (2005)[http://www.nature.com/nmeth/journal/v2/n6/abs/nmeth765.html]. All our derivatives contain the Tn7-L and Tn7-R ends, an antibiotic resistance gene flanked by FRTs and the prefix/suffix BioBrick-compatible multi-cloning site (Figure 1a). Constructs will be available in derivatives of pUC18-Sfi, (high copy number, replicative in any E. coli strain), or derivatives of pUC18-R6KT (medium copy number, replicative only in E. coli strains expressing the pir gene). Specialized miniTn7 vectors containing promoters for gene expression or reporters for expression measurement will also be constructed. In addition, we will provide a portable attTn7 (Tn7 attachment site) to allow using the miniTn7 BioBrick toolkit in any organism as well as in plasmids.
