Structure and evolution-guided design of minimal RNA-guided nucleases · P. Skopintsev et al.
原文开头
We reasoned that inverse protein-folding models (17–19), a structure-conditioned approach, coupled with evolutionary information could generate highly diverse proteins while retaining function. To test the potential of such a design strategy, we selected TnpB, a diverse family of small transposon-encoded ancestors of CRISPR-Cas12 nucleases that mediate RNA-guided DNA cleavage, transcriptional regulation, and genome targeting across all kingdoms of life (23–29). These features render TnpBs as a promising scaffold for exploring RNA-guided nucleases not produced by natural evolution. Petr Skopintsev1,2†, Isabel Esain-Garcia1,2†, Evan C. DeTurk1,2†‡, Peter H.
