tRNA(Asp) with its anticodon mutated to CUA (base pairing stop codon UAG) and under the control of aspV promoter. This biobrick is constructed first by cloning the tRNA(Asp) from AspV in E.coli, then the anticodon region is site-directed mutated.


Construction of BBa_K567013

This biobrick is constructed first by cloning the tRNAAsp from AspV in E.coli, then the anticodon region is site-directed mutated. This part is constructed on the backbone plasmid pACYC184.

Characterization of BBa_K567013

This part acts as a stop codon suppressor tRNA. It can be charged with Asp.

We have used Pbla-Luc-TAG as our Reporter. The amount of luciferase produced is reflected using the bioluminescence emitted during the luciferin reaction. Our results demonstrate that this part can suppress TAG insertion into luciferase. In the experimental group, with the help of BBa_K567011 PT7-TDRS (Favorite Part), luciferase-TAG was produced and bioluminescence was emitted during the luciferin reaction. These results proved that this tRNAAsp can effectively suppress stop codon.

fig. Functional Analysis of Stop-Codon Switch. ER2566 cannot produce luciferase with BBa_K567003 Pbla-Luc-TAG only. When BBa_K567011 PT7-TDRS (Favorite Part) and BBa_K567013 tRNAAsp-TAG (Favorite Part) are also transformed into the cell, luciferase is produced. The results proved Stop-Codon Switch as a strict molecular switch without background noise.This tRNAAsp is part of the Stop-Codon Switch
