Part:BBa_K411003:Experience
ZJU-China 2012 tests K411003
The 8 different concentration of theophylline comparision on part K411003 theophylline robswitch tagged with GFP. Excitation at 480nm and emission at 535nm. Up to 10mM theophylline, cells didn’t show obvious side effects and GFP production is proportioned with theophylline concentration, showing that K411003 is an effective riboswitch which can be regulated by theophylline. When theophylline concentration is beyond a certain degree (about 10 mM), it somewhat affect cell growth and GFP production.
Results show that this is an effecitve riboswitch regulated by theophylline.
We improve this kind of part, embed an RNA scaffold after similar theophylline aptamer and use split GFP to test how theophylline affect the 3D structure of whole RNA.
