Improved Part
According to the problem we mentioned in the demonstration, the expression of the NicA2 protein may be toxic to
Therefore, in addition to the transformation of
Regardless of the type of cloning, screening markers are indispensable, and our part Baa_ have improved one of the most widely used parts Baa_J04450 in iGEM. lacI is present on the genome of many host cells, which suggests that he normal expression of RFP requires the induction of IPTG and need 18 hours of waiting. We replaced the lac promoter in front of the RFP gene with the strong pf-5 promoter PampC. And hope that RFP, as a visible marker for the naked eye, can be expressed more pronouncedly and faster in in
