Purpose

The Calgary iGEM 2013 team sought to detect pathogenic enterohemorrhagic E. coli (EHEC) DNA using pairs of TALEs designed to pathogenic E. coli markers. This TALE was designed based on a sequence alignment of the stx2 gene found in EHEC organisms. It binds to a 19 bp region of the toxin, will detect EHEC strains including E. coli O157:H7, as well as several other EHEC strains. This TALE, along with the complementary BBa_K1189033, will eventually be integrated into the final lateral flow strip FerriTALE prototype.

Design details

The sequence includes a KasI restriction enzyme cut site so that other TALEs may be substituted with the C-terminal linker and K coil. This is one element in which the 2013 Calgary team attempted to make their DNA detection system modular and useful for detection of other DNA sequences based on the selection of an appropriate TALE. The target site was specifically selected to increase binding strength of the TALE to DNA as per Meckler et al. (2013). Please see the iGEM Calgary 2013 Wiki for more details about how these TALEs were engineered for optimal binding.
