Leading CRISPR-Cas technologies employ Cas9 and Cas12 enzymes that generate RNA-guided dsDNA breaks. Yet, the most abundant microbial adaptive immune systems, Type I CRISPRs, are under-exploited for eukaryotic applications. Here we report the adoption of a minimal CRISPR-Cas3 from Neisseria lactamica (Nla) Type I-C system, to create targeted large deletions in the human genome. RNP delivery of its processive Cas3 nuclease and target recognition complex Cascade can confer ~95% editing efficiency. Unexpectedly, NlaCascade assembly in bacteria requires internal translation of a hidden component Cas11 from within the cas8 gene. Furthermore, expressing a separately encoded NlaCas11 is the key to enable plasmid- and mRNA- based editing in human cells. Finally, we demonstrate that supplying cas11 is a universal strategy to systematically implement divergent I-C, I-D, and I-B CRISPR-Cas3 editors with compact sizes, distinct PAM preferences and guide orthogonality. These findings greatly expand our ability to engineer long-range genome edits. Tan et al. discover a miniature CRISPR-Cas3 system that can efficiently create targeted large deletions in human genome. An inconspicuous subunit of its Cas machinery, Cas11, is encoded by a hidden ORF embedded in the cas operon. In human cells, Cas11 is the key enabler for compact CRISPR-Cas3 gene editors.
