Description
A riboswitch which is comprised of an aptamer which recognizes the ligand, theophylline. The riboswitch also contains an RBS. In the absence of theophylline, there is extensive base pairing in the 5' untranslated region (UTR) which blocks the RBS. This base pairing prevents translation of a gene downstream to the riboswitch. In the presence of theophylline, the transcript adopts a secondary structure in which the RBS is exposed, allowing translation to occur.
Notes
The part must be directly fused to the starting codon of the downstream coding region.
