Transcription regulation of restriction-modification system Esp1396I [PDF]

open access: yesNucleic Acids Research, 2009
Abstract The convergently transcribed restriction (R) and methylase (M) genes of the Restriction–Modification system Esp1396I are tightly regulated by a controller (C) protein that forms part of the CR operon. We have mapped the transcriptional start sites from each promoter and examined the regulatory role of C.Esp1396I in vivo and in ...

Rapid PCR Detection of Staphylococcus aureus Clonal Complex 398 by Targeting the Restriction-Modification System Carrying sau1-hsdS1 [PDF]

open access: yes, 2011
A PCR targeting sau1-hsdS1 was developed for rapid detection of Staphylococcus aureus clonal complex 398 (CC398). High sensitivity (100%) and specificity (100%) were shown by evaluating the test on a large strain collection (n = 1,307). We recommend this

Organization of restriction-modification systems

open access: yesNucleic Acids Research, 1991
The genes for over 100 restriction-modification systems have now been cloned, and approximately one-half have been sequenced. Despite their similar function, they are exceedingly heterogeneous. The heterogeneity is evident at three levels: in the gene arrangements; in the enzyme compositions; and in the protein sequences. This paper summarizes the main

To be or not to be: regulation of restriction–modification systems and other toxin–antitoxin systems [PDF]

open access: yesNucleic Acids Research, 2013
One of the simplest classes of genes involved in programmed death is that containing the toxin-antitoxin (TA) systems of prokaryotes. These systems are composed of an intracellular toxin and an antitoxin that neutralizes its effect. These systems, now classified into five types, were initially discovered because some of them allow the stable ...

Epigenetic Regulation of Virulence and Immunoevasion by Phase-Variable Restriction-Modification Systems in Bacterial Pathogens

open access: yes, 2020
Human-adapted bacterial pathogens use a mechanism called phase variation to randomly switch the expression of individual genes to generate a phenotypically diverse population to adapt to challenges within and between human hosts.

Burkholderia pseudomallei sequencing identifies genomic clades with distinct recombination, accessory, and epigenetic profiles. [PDF]

open access: yes, 2014
Burkholderia pseudomallei (Bp) is the causative agent of the infectious disease melioidosis. To investigate population diversity, recombination, and horizontal gene transfer in closely related Bp isolates, we performed whole-genome sequencing (WGS) on ...

SDM-assist software to design site-directed mutagenesis primers introducing "silent" restriction sites [PDF]

open access: yes, 2013
BACKGROUND:Over the past decades site-directed mutagenesis (SDM) has become an indispensable tool for biological structure-function studies. In principle, SDM uses modified primer pairs in a PCR reaction to introduce a mutation in a cDNA insert.

Avoidance of recognition sites of restriction-modification systems is a widespread but not universal anti-restriction strategy of prokaryotic viruses

open access: yesBMC Genomics, 2018
Background Restriction-modification (R-M) systems protect bacteria and archaea from attacks by bacteriophages and archaeal viruses. An R-M system specifically recognizes short sites in foreign DNA and cleaves it, while such sites in the host DNA are ...

The Neisseria gonorrhoeae S.NgoVIII restriction/modification system: a type IIs system homologous to the Haemophilus parahaemolyticus HphI restriction/modification system [PDF]

open access: yesNucleic Acids Research, 1997
Strains of Neisseria gonorrhoeae possess numerous restriction-modification (R-M) systems. One of these systems, which has been found in all strains tested, encodes the S. NgoVIII specificity (5'TCACC 3') R-M system. We cloned two adjacent methyltransferase genes (dcmH and damH), each encoding proteins whose actions protect DNA from digestion by R.HphI ...
