    tRNA Modulator System

    • System Analysis

    tRNA Modulator + Reporter for Qualitative Analysis

    Action: when rare tRNAArg is over expressed, the amount of tRNAArg in the tRNA pool is largely increased, which facilitates ribosome to get through the tandem of AGG codons in the RFP's mRNA.

    tRNA Modulator + Reporter for Quantitative Analysis

    Action: when rare tRNAArg is over expressed, the amount of tRNAArg in the tRNA pool is largely increased, which facilitates ribosome to get through the tandem of AGG codons in the modified luciferase's mRNA.

    • Conclusion

    We have analyzed the three potential factors influencing Rare-Codon Switch and have fully characterized our device through working curves, demonstrating the function of this device as a regulating tool for protein biosynthesis. We have also identified influential factors other than the three proposed above.

    aaRS Modulator System

    • System Analysis

    aaRS Modulator + Reporter for Qualitative Analysis

    Action: When TDRS is expressed under IPTG induction, it can charge tRNAAsp-AGG with Asp. tRNAAsp-AGG then recognizes the rare codon AGG on RFP's mRNA and add Asp to the polypeptide chain. RFP is expressed.

    aaRS Modulator + Reporter for Quantitative analysis

    Action: When TDRS is expressed under IPTG induction, it can charge tRNAAsp-AGG with Asp. tRNAAsp-AGG then recognizes the rare codon AGG on the modified luciferase's mRNA and add Asp to the polypeptide chain. Modified luciferase is expressed.

    • Conclusion

    We have designed modified AspRS and tested its aminoacylation ability, ensuring the function of our Rare-Codon Switch.
