CRISPR/Cpf1 enables fast and simple genome editing of Saccharomyces cerevisiae.

ABSTRACT: Cpf1 represents a novel single RNA-guided CRISPR/Cas endonuclease system suitable for genome editing with distinct features compared with Cas9. We demonstrate the functionality of three Cpf1 orthologues - Acidaminococcus spp. BV3L6 (AsCpf1), Lachnospiraceae bacterium ND2006 (LbCpf1) and Francisella novicida U112 (FnCpf1) - for genome editing of Saccharomyces cerevisiae. These Cpf1-based systems enable fast and reliable introduction of donor DNA on the genome using a two-plasmid-based editing approach together with linear donor DNA. LbCpf1 and FnCpf1 displayed editing efficiencies comparable with the CRISPR/Cas9 system, whereas AsCpf1 editing efficiency was lower. Further characterization showed that AsCpf1 and LbCpf1 displayed a preference for their cognate crRNA, while FnCpf1-mediated edi
