Design Notes

We added an eGFP sequence taken from BBa_K598009 downstream of our atrazine riboswitch (BBa_M50048) so that the riboswitch would control translation of the eGFP. When we ordered the construct, DNA 2.0 also added an IPTG-inducible promoter to the beginning of our sequence. Typically, an RBS follows the promoter that is added to a plasmid. However, in this situation an RBS would be redundant and interfere with our riboswitch function; if there is an RBS before the UTR and aptamer, a ribosome could bind there and disrupt the shape of the riboswitch. For this reason, it was necessary to request a custom plasmid design that did not include the standard RBS.
