| Name | CRISPR system, Dpsyc subtype |
| Type | SYSTEM |
| Description | CRISPR repeats are by definition Clustered Regularly Interspaced Short
Palindromic Repeats, described by Jansen [1]. Certain proteins, including Cas1 to Cas4, are found only in genomes with CRISPR repeats, and are near these repeats. Haft, et al. have now found multiple subtypes of CRISPR/cas systems. This property describes a subtype found in Desulfotalea psychrophila LSv54, Geobacter sulfurreducens PCA, Gemmata obscuriglobus UQM 2246, Verrucomicrobium spinosum DSM 4136, and Actinomyces naeslundii MG1. Cas1 tends to be fused with Cas4 in this type. Repeats typically are 37 base pairs long. |
