WebAug 16, 2016 · Cytosine base editing The beginnings of cytosine base editing Komor created the first cytosine base editor by coupling a cytidine deaminase with the inactive dCas9 (Komor et al., 2016). These fusions convert cytosine to uracil without cutting DNA. Uracil is then subsequently converted to thymine through DNA replication or repair. WebCytosine base editing. (a)Cytosine deamination generates uracil, which base pairs as thymidine. R = 2′-deoxyribose in DNA, or ribose in RNA. (b)Cytosine base editing strategy by BE1, BE2, BE3, or BE4. R-loop formation exposes a region of single-stranded DNA to the cytidine deaminase domain.
