Rosewood DmTrnL-UAA Trigger 1.2 transcription unit
This part is a transcription unit of the Rosewood DmTrnL-UAA Trigger 1.2 (BBa_K3453062) for sequence-based detection of rosewood. The transcription is controlled by the T7 promoter (BBa_K2150031) and the strong SBa_000587 synthetic terminator (BBa_K3453000).
Usage and Biology
A toehold switch is an RNA–based device containing a ribosome binding site (RBS) and an ATG start codon embedded in a hairpin structure that blocks translation initiation [1]. The hairpin can be unfolded upon binding of a trigger RNA therefore exposing the RBS and the ATG start codon permitting translation of the reporter protein (Figure 1).
Figure 1. Toehold switches principle.
This part is a transcription unit of BBa_K3453062 which is a trigger for the Rosewood DmTrnL-UAA Toehold Switch 1.2 (BBa_K3453052) and also contains the switch binding site for the Rosewood DmTrnL-UAA Toehold 2.3 (BBa_K3453056).
This part proved to be functional: the transcribed rosewood RNA was able to bind to the Rosewood DmTrnL-UAA Toehold Switch 2.3 and a readable output was generated. However, the Rosewood DmTrnL-UAA Toehold Switch 1.2 turned out to be not functional and the interaction with this switch could not be assessed.
Full results are available on the BBa_K3453152 and BBa_K3453156 pages in the registry.
