Description
This part is a synthetic riboswitch that can be used in E. coli. In the presence of theophylline, the expression of the gene of interest is induced, but in the absence of theophylline, very little transcription takes place. This part contains a modified T5 promoter, which, in the absence of cymR, acts as a strong constitutive promoter. The ribosomal binding site is contained in the riboswitch.
Notes
Because the riboswitch must be directly beside the gene of interest (the start codon is used in the folding of the riboswitch), we added a BsaI recognition site. This allows the riboswitch to be connected directly to a gene of interest using the Golden Gate Assembly method (if the first nucleotide after the start codon of the gene of interest is a C, we made it for use with superfolder GFP).
