Part:BBa_K3453141
Rosewood DmRbcL Trigger 1.1 transcription unit
This part is a transcription unit of the Rosewood DmRbcL Trigger 1.1 (BBa_K3453041) 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 thereby exposing the RBS and the ATG start codon permitting translation of the reporter protein (Figure 1).

This part is a transcription unit of BBa_K3453041 which is a trigger for the Rosewood DmRbcL Toehold Switch 1.1 (BBa_K3453031).
This part proved to be functional: the transcribed rosewood RNA was able to bind to the corresponding toehold switch and a readable output was generated.
Full results are available on the BBa_K3453131 page in the registry.
