Description
Residues 44-117 of the tolR protein from E. coli, with added start and double stops. Overexpression of this part is known to stimulate formation of outer-membrane vesicles (OMVs) (Henry et al., 2004).
Notes
As the sequence came from E. coli's genome, evolution has likely already made it codon optimised. However, this is only a single domain of the protein, hence start and stop codons had to be artificially added to ensure it is a proper coding sequence. A previous team attempted to submit this part to the registry (BBa_K257005, by Paris 2009), but forgot to add the start codon; we thus submit this part to amend that error.
Another improvement we made was to add a second stop codon at the c-terminus, to more stringently terminate translation.

Derived from the genomic sequence of E. coli K12, but with added N-terminal ATG (to start translation), and C-terminal TAATAA (to stop translation).
