Cas9

Cas9 is the RNA-guided DNA endonuclease used by the CRISPR(clustered regularly interspaced short palindromic repeats)-associated systems to generate double-strand DNA breaks in the invading DNA during an adaptive bacterial immune response.

It has been exploited for use in genome editing systems.
