Bacteria are under constant predation from viruses, called bacteriophages (phages). This
threat has driven the evolution of multiple defense systems, including the CRISPR-Cas …

CRISPR (clustered regularly interspaced short palindromic repeats)–Cas (CRISPR-
associated) is an adaptive immunity system in bacteria and archaea that functions via a …

In the type III CRISPR–Cas immune response of prokaryotes, infection triggers the
production of cyclic oligoadenylates that bind and activate proteins that contain a CARF …

CRISPR–Cas is a prokaryotic adaptive immune system that functions by incorporating
fragments of foreign DNA into CRISPR arrays. The arrays containing spacers derived from …

CRISPR-Cas systems are adaptive immune systems that protect prokaryotes from foreign
nucleic acids, such as bacteriophages. Two of the most prevalent CRISPR-Cas systems …

CRISPR–Cas systems constitute the adaptive immune system of bacteria and archaea, as a
sequence-specific nucleic acid targeting defense mechanism. The sequence-specific …

Bacteria possess an array of defenses against foreign invaders, including a broadly
distributed bacteriophage defense system termed CBASS (cyclic oligonucleotide-based anti …

Bacterial adaptive immunity utilizes RNA-guided surveillance complexes comprising Cas
proteins together with CRISPR RNAs (crRNAs) to target foreign nucleic acids for destruction …

Clustered regularly interspaced short palindromic repeats (CRISPRs), together with an
operon of CRISPR-associated (Cas) proteins, form an RNA-based prokaryotic immune …

CRISPR-Cas immune systems function to defend prokaryotes against potentially harmful
