Description
Codes for an RNA secondary structure that, in the presence of theophylline, undergoes a conformational change that makes the previously sequestered ribosome binding site available for binding thus allowing for transcription of the downstream sequence. Nominal induction levels for theophylline are 0 to 10 mM. Achieves an 59 - fold activation ratio in 1 mM theophylline as reported by Gallivan and Lynch in 'A flow cytometry based screen for synthetic riboswitches.' Nucleic Acids Res. 2009 January; 37(1): 184???192.
Notes
None.
