An Endogenous Staphylococcus aureus CRISPR-Cas System Limits Phage Proliferation and Is Efficiently Excised from the Genome as Part of the SCCmec Cassette

open access: yesMicrobiology Spectrum, 2023
CRISPR-Cas is an adaptive immune system that allows bacteria to inactivate mobile genetic elements. Approximately 50% of bacteria harbor CRISPR-Cas; however, in the human pathogen Staphylococcus aureus, CRISPR-Cas loci are less common and often studied ...

Optimization of CRISPR–Cas system for clinical cancer therapy

open access: yesBioengineering & Translational Medicine, 2023
Cancer is a genetic disease caused by alterations in genome and epigenome and is one of the leading causes for death worldwide. The exploration of disease development and therapeutic strategies at the genetic level have become the key to the treatment of

A global comprehensive study of the distribution of type I-E and type I-E* CRISPR-Cas systems in Klebsiella pneumoniae

open access: yesIndian Journal of Community Medicine, 2023
Background: The CRISPR-Cas (clustered regularly interspaced short palindromic repeats–CRISPR-associated proteins) systems are the short DNA sequences and RNA-dependent nuclease involved in the adaptive immunity in bacteria and archaea. The type of CRISPR-

Structural studies of CRISPR-associated proteins [PDF]

open access: yes, 2013
Clustered regularly interspaced short palindromic repeats (CRISPRs) act to prevent viral infection and horizontal gene transfer in prokaryotes. The genomic CRISPR array contains short sequences (“spacers”) that are derived from foreign genetic elements ...

Viral Diversity Threshold for Adaptive Immunity in Prokaryotes

open access: yesmBio, 2012
Bacteria and archaea face continual onslaughts of rapidly diversifying viruses and plasmids. Many prokaryotes maintain adaptive immune systems known as clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated genes (Cas ...

Research advances on pathogenic nucleic acid detection technology based on CRIPSR/Cas system

open access: yes浙江大学学报. 农业与生命科学版, 2023
Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) (CRISPR/Cas) system, an ancient bacterial and archaeal immune system, has rapidly developed into a popular gene-editing tool, which largely promotes the ...
