CRISPR-Cas immune systems function to defend prokaryotes against potentially harmful mobile genetic elements including viruses and plasmids. The multiple CRISPR-Cas systems (Types I, II, III) each recognize and target destruction of foreign invader nucleic acids via structurally and functionally div...

In this work, we analyzed recognized PAM sequences from four CRISPR-Cas systems: E. coli I-E, B. halodurans I-C, S. thermophilus CR1 II-A, and F. novicida V. Cells containing functional PAMs were sorted using FACS and subsequently sequenced. Ranking of recognized PAMs from a positive screen

Deep sequencing data for PAM-SCANR tested CRISPR-Cas systems
Characteristic for type III CRISPR-Cas systems is the generation of cyclic oligoadenylate (cOA) molecules, which allosterically activate proteins carrying cognate sensory domains: CARF or SAVED. Here, we characterize a type III-B system associated set of genes from Haliangium ochraceum, containing t...
