Structures of the type I DNA restriction enzymes. [PDF]

open access: yesProc Natl Acad Sci U S A, 2017
The article by Liu et al. (1) on the structure of type I DNA restriction and modification enzymes purports to significantly advance our understanding of these enzymes and proposes a model for their operation. While the partial structure of one of these enzymes is interesting and defines the interface between some of the subunits, the article contains ...

Structure and operation of the DNA-translocating type I DNA restriction enzymes. [PDF]

open access: yesGenes Dev, 2012
Type I DNA restriction/modification (RM) enzymes are molecular machines found in the majority of bacterial species. Their early discovery paved the way for the development of genetic engineering. They control (restrict) the influx of foreign DNA via horizontal gene transfer into the bacterium while maintaining sequence-specific methylation ...

Historical Aspects of Restriction Endonucleases as Intelligent Scissors for Genetic Engineering

open access: yesFermentation, 2023
Restriction endonucleases are a component of restriction–modification systems, where the main biological function is to protect bacterial cells from incoming foreign DNA molecules.

Restriction enzyme digestion of hemimethylated DNA [PDF]

open access: yesNucleic Acids Research, 1981
Hemimethylated duplex DNA of the bacteriophage phi X 174 was synthesized using primed repair synthesis is in vitro with E. coli DNA polymerase I followed by ligation to produce the covalently closed circular duplex (RFI). Single-stranded phi X DNA was used as a template, a synthetic oligonucleotide as primer and 5-methyldeoxycytidine-5'-triphosphate ...

NEBcutter: a program to cleave DNA with restriction enzymes [PDF]

open access: yesNucleic Acids Research, 2003
NEBcutter, version 1.0, is a program available via a web server (http://tools.neb.com/NEBcutter) that will accept an input DNA sequence and produce a comprehensive report of the restriction enzymes that will cleave the sequence. It produces a variety of outputs including restriction enzyme maps, theoretical digests and links into the restriction enzyme

In vitro Type II Restriction of Bacteriophage DNA With Modified Pyrimidines

open access: yesFrontiers in Microbiology, 2020
To counteract host-encoded restriction systems, bacteriophages (phages) incorporate modified bases in their genomes. For example, phages carry in their genomes modified pyrimidines such as 5-hydroxymethyl-cytosine (5hmC) in T4gt deficient in α- and β ...

Revised selection criteria for candidate restriction enzymes in genome walking. [PDF]

open access: yesPLoS ONE, 2012
A new method to improve the efficiency of flanking sequence identification by genome walking was developed based on an expanded, sequential list of criteria for selecting candidate enzymes, plus several other optimization steps.
