SAT toehold switch RNA sensor

SAT toehold switch RNA sensor


Usage and Biology

Toehold switch is a secondary structure of RNA. Because of special sequence design, it can form a hairpin structure and hide ribosome binding site (RBS)in the loop. There are three basic elements of toehold switches including 30bp trigger sequence(GCACCTAACCGTTCAATAACATAGAACTCC), bacteria ribosome binding site and linker.The trigger sequence of this part is complementary to a part of Signal Transducer and Activator of Transcription (SAT) mRNA(SAT partial sequence, BBa_K1728007). Once the SAT mRNA is presented, the toehold structure will open. Therefore, the ribosome is able to bind on the RBS and translate the down stream gene.
