Design Notes
Based on the characterization results, we found that although pprm1 possesses three PREs, it has a low induced expression level which indicates a good potential for transformation. And the background expression level of this promoter is low which means it can be used to express some proteins that require lower concentrations in specific stage. Based on the literature, we learned the general effect of PREs on promoter strength. For example, an increase in the copy number of PREs can enhance the induced expression level of the promoter. We doubled the 3 × PREs sequence in natural pprm1. The modified pprm1 is referred to as pprm1 Ultra which contains 6 × PREs.
