Design Notes
The gene traI(K34G) is derived from Agrobacterium tumefaciens and encode a enzyme necessary for synthesizing Quorum Sensing signaling molecules ([N-]acyl-homoserine lactones, AHLs), 3OC8 HSL (hereafter C8), in E. coli. This part constitutively produces C8. We introduced point mutation to traI gene and the productivity of C8 was improved by approximately 3-fold. We introduced this part to E. coli then E. coli could produced enough C8 to induce transcription of human cells.
The mutation was introduced wild type traI(BBa_K553001).
The DNA sequences of traI (K34G) is optimized for expressing in E. coli considering the codon usage.
