Part:BBa_K191007

Trp promoter

Promoter of Tryptophan operon ( Tryptophan operon is an operon that codes for the components of tryptophan's synthesis)

Usage and Biology

Presence of Tryptophan inhibits the expression of genes downstream of the regulator. As the hybrid protein LovTAP ( BBa_K191006 ) contains the corresponding regulatory domain, LovTAP can also bind to the regulator and and interferes with downstream gene's expression.

Contribution from LCG-Global 2024

This year, our project focused on the development of a standardized biomarker detection system. This part serves as the sensitive promoter in the R module of our tryptophan detection system:

By combining it with our A module, we validated the design of our standardized system and achieved a response to different concentrations of tryptophan:

Additionally, we performed a Hill equation fit for this system:

Our work provides more insights into the response intensity of this part under varying tryptophan concentrations, offering valuable references for future iGEM teams.
