Activity of DmoCre mutants with altered specificity in both I-DmoI and I-CreI subdomains. (a) Extrachromosomal assay in CHO-K1 cells. Cells were transfected with different meganucleases or an empty vector and the cleavage against the two D2-Ca and D(4AGT)-Ca (targets was measured). The nucleotides in the D(4AGT)-Ca target for which the specificity has been modified have been gray boxed. (b) Extrachromosomal assay in CHO-K1 cells. Cells were transfected with different meganucleases or an empty vector (mock) and the cleavage against the two D2-Cb and D(4AGT)-Cb targets was measured. The nucleotides in the D(4AGT)-Cb target for which the specificity has been modified have been gray boxed.
