Evaluation of a Quantitative DNA Methylation Analysis Technique using Methylation-Sensitive/Dependent Restriction Enzymes and Real-Time PCR [PDF]

open access: bronzeEpigenetics, 2006
DNA methylation in mammals has been shown to play many important roles in diverse biological phenomena. Several methods have been developed for the measurement of region-specific levels of DNA methylation.

Using nucleolytic toxins as restriction enzymes enables new RNA applications. [PDF]

open access: yesNucleic Acids Res
Over the past five decades, DNA restriction enzymes have revolutionized biotechnology. While these enzymes are widely used in DNA research and DNA engineering, the emerging field of RNA and mRNA therapeutics requires sequence-specific RNA ...

Site-specific DNA transesterification catalyzed by a restriction enzyme [PDF]

open access: greenProceedings of the National Academy of Sciences, 2007
Most restriction endonucleases use Mg 2+ to hydrolyze phosphodiester bonds at specific DNA sites. We show here that BfiI, a metal-independent restriction enzyme from the phospholipase D superfamily, catalyzes both DNA hydrolysis and transesterification reactions at its recognition site.

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 ...

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 ...

Topological digestion drives time-varying rheology of entangled DNA fluids [PDF]

open access: yes, 2021
Understanding and controlling the rheology of polymeric complex fluids that are pushed out-of-equilibrium is a fundamental problem in both industry and biology. For example, to package, repair, and replicate DNA, cells use enzymes to constantly manipulate DNA topology, length, and structure.

Type I restriction endonucleases are true catalytic enzymes [PDF]

open access: yes, 2009
Type I restriction endonucleases are intriguing, multifunctional complexes that restrict DNA randomly, at sites distant from the target sequence. Restriction at distant sites is facilitated by ATP hydrolysis-dependent, translocation of double-stranded ...
