CRISPR-Cas adaptation in Escherichia coli requires RecBCD helicase but not nuclease activity, is independent of homologous recombination, and is antagonized by 5' ssDNA exonucleases
(2018)
Journal Article
© The Author(s) 2018. Prokaryotic adaptive immunity is established against mobile genetic elements (MGEs) by 'naïve adaptation' when DNA fragments from a newly encountered MGE are integrated into CRISPR-Cas systems. In Escherichia coli, DNA integrati...
