| Type | SYSTEM |
| Description | CRISPR repeats are by definition Clustered Regularly Interspaced Short Palindromic Repeats. The repeats vary in size from 24 to 48 bp, interspaced by similarly sized non-repetitive sequences. These spacers often are derived from phage and other exogenous DNA, are transcribed into RNA, and confer resistance to those same phage. Several CRISPR-associated sequences (cas genes) are nearly as widespread as CRISPR itself and nearly always are found near repeat loci. Others represent minor cas genes that serve as markers for specific subtypes of CRISPR/cas system, each with characteristic cas gene makeup, repeat structure, and spacer length. The PreFran subtype is found in multiple reference genomes of Prevotella and Francisella, and found also in several additional species. It has a single long protein, Cpf1 (Cas protein 1 of PreFran subtype), in addition to Cas4, Cas1, and Cas2. The typical repeat has length 36. |
