Summary: Testing its gene editing efficiency in BL21 (DE3)

Characterization from iGEM21-NNU-China

        Cytosine base editors (CBEs) enable targeted C•G-to-T•A conversions in genomic DNA, consisting of dSpCas9, CDA, and UGI. It was first registered in 2020. In order to test the editing efficiency of this composite part, we construct the dual plasmid system based on the (BBa_K3645011). We selected the cadA, maeA, and maeB genes as the testing sites, and the related pTarget plasmids were constructed. Results showed that the (BBa_K3645011) can successfully work in the BL21 (DE3), and the editing efficiency of single gene editing, double genes editing and triple genes editing can reach 85%, 56% and 25%, respectively (Fig. 1). These results provide references for future iGEM teams to choose gene-editing tools in E.coli.
