Plasmid pEC156, a Naturally Occurring Escherichia coli Genetic Element That Carries Genes of the EcoVIII Restriction-Modification System, Is Mobilizable among Enterobacteria. [PDF]
PLoS ONE, 2016 Type II restriction-modification systems are ubiquitous in prokaryotes. Some of them are present in naturally occurring plasmids, which may facilitate the spread of these systems in bacterial populations by horizontal gene transfer.

PLoS Genetics, 2022 Understanding mechanisms that shape horizontal exchange in prokaryotes is a key problem in biology. A major limit on DNA entry is imposed by restriction-modification (RM) processes that depend on the pattern of DNA modification at host-specified sites ...

Restriction modification systems as engines of diversity [PDF]
Frontiers in Microbiology, 2015 Restriction modification (RM) systems provide protection against a broad spectrum of phages. However, the likelihood of a phage permanently bypassing this can be as high as 0.1 per infection (Korona et al., 1993) which makes for a relatively weak defense.

Individual- and Population-based Diversity in Restriction-modification Systems
Bulletin of Mathematical Biology, 2000 Restriction-modification (RM) systems are cognate gene complexes that code for an endonuclease and a methylase. They are often thought to have developed in bacteria as protection against invading genetic material, e.g., phage DNA. The high diversity of RM systems, as observed in nature, is often ascribed to the coevolution of RM systems (which 'invent'

A Survey of Archaeal Restriction–Modification Systems
Microorganisms, 2023 When compared with bacteria, relatively little is known about the restriction–modification (RM) systems of archaea, particularly those in taxa outside of the haloarchaea. To improve our understanding of archaeal RM systems, we surveyed REBASE, the restriction enzyme database, to catalog what is known about the genes and activities present in the 519 ...

Frontiers in Microbiology, 2020 Campylobacter jejuni is a major cause of foodborne gastroenteritis worldwide inflicting palpable socioeconomic costs. The ability of this pathogen to successfully infect its hosts is determined not only by the presence of specific virulence genes but ...

A Type III restriction–modification system in Mycoplasma mycoides subsp. capri [PDF]
Open Biology, 2012 The sequenced genome of Mycoplasma mycoides subsp. capri revealed the presence of a Type III restriction–modification system (MmyCI). The methyltransferase (modification) subunit of MmyCI (M.MmyCI) was shown to recognize the sequence 5′-TGAG-3′ and ...
