Random guide-independent DNA cleavage from the Argonaute of Exiguobacterium sp. AB2

These findings suggest that EsAgo functions as a DNA-interfering nuclease with or without DNA guides. Within the cell, it is possible that EsAgo utilizes this mechanism to screen and destroy foreign genetic elements. Moreover, the potential capacity for specific dsDNA cleavage at moderate temperatures gives rise to intriguing possibilities of repurposing EsAgo as a programmable nuclease for future biotechnological use.
