Engineered endonucleases are a powerful tool for editing DNA. However, sequence
preferences may limit their application. We engineer a structure-guided
endonuclease (SGN) composed of flap endonuclease-1 (FEN-1), which recognizes the
3' flap structure, and the cleavage domain of Fok I (Fn1), which cleaves DNA
strands. The SGN recognizes the target DNA on the basis of the 3' flap structure
formed between the target and the guide DNA (gDNA) and cut the target through its
Fn1 dimerization. Our results show that the SGN, guided by a pair of gDNAs,
cleaves transgenic reporter gene and endogenous genes in zebrafish embryonic
genome.
