Abstract

A recent publication by Thuronyi et al. described a directed evolution system called phage-assisted continuous evolution (PACE) that was used to generate improved variants of CRISPR-Cas9 base editors. These evolved base editors overcome some of the inherent limitations of the technology such as sequence context preferences, restricted editing windows, and large construct sizes.
