Optimizing ErCas12a for efficient gene editing in Arabidopsis thaliana.

ABSTRACT: The ErCas12a nuclease, also known as MAD7, is part of a CRISPR/Cas system from Eubacterium rectale and distantly related to Cas12a nucleases. As it shares only 31% sequence homology with the commonly used AsCas12a, its intellectual property may not be covered by the granted patent rights for Cas12a nucleases. Thus, ErCas12a became an attractive alternative for practical applications. However, the editing efficiency of ErCas12a is strongly target sequence- and temperature-dependent. Therefore, optimization of the enzyme activity through protein engineering is especially attractive for its application in plants, as they are cultivated at lower temperatures. Based on the knowledge obtained from the optimization of Cas12a nucleases, we opted to improve the gene editing efficiency of ErCas12a b
