NettetTo address this technical challenge, we developed a strategy based on split inteins that splits the required CRISPR/Cas9 components across a dual-vector system. The CRISPR/Cas reassembles into an active form following co-infection to achieve targeted genome editing in plant cells. NettetThe smallest known intein, found in the ribonucleoside diphosphate reductase gene of Methanobacterium thermoautotrophicum (Mth RIR1 intein), was found to splice poorly in Escherichia coli with the naturally occurring proline residue adjacent to the N-terminal cysteine of the intein. Splicing proficiency increased when this proline was replaced …
