The majority of archaea encode CRISPR-Cas systems but only a few CRISPR-Cas-based genetic tools have been developed for organisms from this domain. Nayak and Metcalf have harnessed a bacterial Cas9 protein for genome editing in Methanosarcina acetivorans, enabling efficient gene deletion and replacement.
