Trove of CRISPR-like gene-cutting enzymes found in microbes

The search for a CRISPR enzyme’s ancestors has revealed more than one million potential genome-editing tools.

By exploring the evolutionary origins of an enzyme used in the CRISPR genome-editing system, researchers have unearthed more than one million other potential editors lurking in microbial genomes. The study, published on 9 September in Science1, found
