New CRISPR-Cas systems discovered
In bacteria and archaea,CRISPRCas adaptive immune systems utilize RNA-guided endonucleases to defend against invasion by foreign nucleic acids of bacteriophage,virus and plasmid origin.In a recent paper published in Nature,Burstein et al.identified the first Cas9 protein in uncultivated archaea and two novel CRISPR-CasX and CRISPR-CasY systems in uncultivated bacteria by capitalizing on analysis of terabasescale metagenomic datasets from natural uncultivated organisms.
