Genome Property Definition Page

NameCRISPR system, Pging subtype
DescriptionCRISPR repeats are by definition Clustered Regularly Interspaced Short Palindromic Repeats. Certain proteins are found only in genomes with CRISPR repeats and are near these repeats. We have shown that certain families of CRISPR-associated (cas) proteins, unlike the cas1-cas4 genes common to nearly all loci, are relatively uncommon and mark distinct subclasses of CRISPR/cas system. This Genome Property describes a rare CRISPR/cas subtype, named Pging for its occurence in Porphyromonas gingivalis W83.
