CommentThis model identifies CRISPR-associated protein Cas1, the most universal CRISPR system protein. CRISPR is an acronym for Clustered Regularly Interspaced Short Palindromic Repeats, a system for heritable host defense by prokaryotic cells against phage and other foreign DNA. Cas1 is a metal-dependent DNA-specific endonuclease.
