NameCRISPR system, Aferr subtype
DescriptionAt least ten different systems of proteins associated associated with CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) have been described, such as the Ecoli, Ypest, Nmeni, and Dvulg subtypes. We designate this type Aferr, after Acidithiobacillus ferrooxidans ATCC 23270, where this system is carried on the chromosome rather than on a plasmid, and where it is the only CRISPR subtype in the species. None of the familiar core cas genes, cas1-cas4, is found in A. ferrooxidans, making this type of CRISPR/cas locus unusual.
