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 [1]. 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.
