CRISPR-Cas Systems in Prokaryotes [PDF]
Polish Journal of Microbiology, 2015 Prokaryotic organisms possess numerous strategies that enable survival in hostile conditions. Among others, these conditions include the invasion of foreign nucleic acids such as bacteriophages and plasmids. The clustered regularly interspaced palindromic repeats-CRISPR-associated proteins (CRISPR-Cas) system provides the majority of bacteria and ...

Adaptation in CRISPR-Cas Systems [PDF]
Molecular Cell, 2016 Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins constitute an adaptive immune system in prokaryotes. The system preserves memories of prior infections by integrating short segments of foreign DNA, termed spacers, into the CRISPR array in a process termed adaptation.

CRISPR-Cas Systems in Streptococci [PDF]
Current Issues in Molecular Biology, 2019 Streptococci are one of the most important and common constituents of the host's microbiota and can colonize and live in the upper respiratory and urogenital tract of humans and animals. The CRISPR-Cas systems (i.e., clustered regularly interspaced short palindromic repeat, with CRISPR-associated proteins) found in bacteria and archaea provide sequence-

The CRISPR-Cas system in Enterobacteriaceae [PDF]
Pathogens and Disease, 2018 In nature, microorganisms are constantly exposed to multiple viral infections and thus have developed many strategies to survive phage attack and invasion by foreign DNA. One of such strategies is the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated proteins (Cas) bacterial immunological system.

CRISPR-Cas systems in multicellular cyanobacteria [PDF]
RNA Biology, 2018 Novel CRISPR-Cas systems possess substantial potential for genome editing and manipulation of gene expression. The types and numbers of CRISPR-Cas systems vary substantially between different organisms. Some filamentous cyanobacteria harbor > 40 different putative CRISPR repeat-spacer cassettes, while the number of cas gene instances is much lower ...

Mechanisms regulating the CRISPR-Cas systems
Frontiers in Microbiology, 2023 The CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats- CRISPR associated proteins) is a prokaryotic system that enables sequence specific recognition and cleavage of nucleic acids. This is possible due to cooperation between CRISPR array which contains short fragments of DNA called spacers that are complimentary to the targeted ...

CRISPR-Cas systems in Proteus mirabilis
Infection, Genetics and Evolution, 2021 The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) is a bacterial defense mechanism against bacteriophages composed of two different parts: the CRISPR array and the Cas genes. The spacer acquisition is done by the adaptation module consisting of the hallmark Cas1 Cas2 proteins, which inserts new spacers into the CRISPR array.

Using CRISPR-Cas systems as antimicrobials [PDF]
Current Opinion in Microbiology, 2017 Although CRISPR-Cas systems naturally evolved to provide adaptive immunity in bacteria and archaea, Cas nucleases can be co-opted to target chromosomal sequences rather than invasive genetic elements. Although genome editing is the primary outcome of self-targeting using CRISPR-based technologies in eukaryotes, self-targeting by CRISPR is typically ...
