 10-155 1.98e-30

CRISPR type I-E/ECOLI-associated protein CasB/Cse2; CRISPR is a term for Clustered, Regularly Interspaced Short Palidromic Repeats. A number of protein families appear only in association with these repeats and are designated Cas (CRISPR-Associated) proteins. This model family is found in Ecoli subtype CRISPR/Cas regions of many bacteria, most of which are mesophiles, and not in Archaea. It was designated Cse2 originally, and renamed CasB based on its characterization in the CASCADE complex.

CRISPR-associated protein Cse2 (CRISPR_cse2); Clusters of short DNA repeats with non-homologous spacers, which are found at regular intervals in the genomes of phylogenetically distinct prokaryotic species, comprise a family with recognisable features. This family is known as CRISPR (short for Clustered, Regularly Interspaced Short Palindromic Repeats). A number of protein families appear only in association with these repeats and are designated Cas (CRISPR-Associated) proteins. This family of proteins, represented by CT1973 from Chlorobaculum tepidum, is encoded by genes found in the CRISPR/Cas subtype Ecoli regions of many bacteria (most of which are mesophiles), and not in Archaea. It is designated Cse2.
