Dependence of post-segregational killing mediated by Type II restriction–modification systems on the lifetime of restriction endonuclease effective activity [PDF]
Plasmid-borne Type II restriction–modification (RM) systems mediate post-segregational killing (PSK). PSK is thought to be caused by the dilution of restriction and modification enzymes during cell division, resulting in accumulation of unmethylated DNA ...

A Survey of Archaeal Restriction–Modification Systems [PDF]
When compared with bacteria, relatively little is known about the restriction–modification (RM) systems of archaea, particularly those in taxa outside of the haloarchaea.

The Restriction–Modification Systems of Clostridium carboxidivorans P7 [PDF]
Clostridium carboxidivorans P7 (DSM 15243) is a bacterium that converts syngas (a mixture of CO, H2, and CO2) into hexanol. An optimized and scaled-up industrial process could therefore provide a renewable source of fuels and chemicals while consuming ...

IS-linked movement of a restriction-modification system. [PDF]
Potential mobility of restriction-modification systems has been suggested by evolutionary/bioinformatic analysis of prokaryotic genomes. Here we demonstrate in vivo movement of a restriction-modification system within a genome under a laboratory ...

The evolutionary replacement of restriction-modification by Ssp antiviral systems is associated with the distribution of prophages in the major clonal group of Acinetobacter baumannii [PDF]
Bacteriophages kill almost half of the world’s bacterial cells every day. In response, bacteria have developed anti-phage defense mechanisms that number in the dozens.

Restriction modification systems in archaea: A panoramic outlook [PDF]
Restriction modification (RM) systems are one of the ubiquitous yet primitive defense responses employed by bacteria and archaea with the primary role of safeguarding themselves against invading bacteriophages.

Restriction-modification systems and prophages drive genomic diversification in Priestia megaterium [PDF]
Bacteria are frequently stressed by bacteriophages. Priestia megaterium is a bacterium of both agricultural and biotechnological importance, yet it has been unclear how the interplay between phage-imposed stress and bacterial immunity shapes the genome ...

Anti-plasmid defense in hypervirulent Klebsiella pneumoniae involves Type I-like and Type IV restriction modification systems [PDF]
Hypervirulent Klebsiella pneumoniae (hvKp) and classical multidrug-resistant (MDR) strains belong to distinct lineages and hvKp are typically characterized by hypermucoid capsules that have been shown to limit horizontal gene transfer (HGT), including ...

Bacterial defense barriers, such as DNA methylation-associated restriction-modification (R-M) and the CRISPR-Cas system, play an important role in bacterial antimicrobial resistance (AMR).

The restriction-modification (RM) systems are compared to a primitive, innate, prokaryotic immune system, controlling the invasion by foreign DNA, composed of methyltransferase (MTase) and restriction endonuclease.
