This entry represents the HEPN domain of Csm6 from bacteria (i.e Enterococcus italicus), a Cas (CRISPR-associated) protein from type III-A CRISPR-Cas system. It consists of a CARF domain at the N-terminal, a six-helix domain and a C-terminal HEPN domain at the C-terminal, which has RNase activity [1].	Domain
