The average spacing of restriction enzyme recognition sites in DNA [PDF]

open access: greenJournal of Theoretical Biology, 1982
The discovery of naturally occurring enzymes which cleave DNA at sites specific to particular nucleotide sequences has had a great impact on molecular biology. The function of these enzymes in uivo is to protect bacterial cells from viral invasion by degradation of foreign DNA.

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.

REBASE—a database for DNA restriction and modification: enzymes, genes and genomes [PDF]

open access: goldNucleic Acids Research, 2009
Abstract REBASE is a comprehensive and extensively curated database of information about the components of restriction-modification (RM) systems. It is fully referenced and provides information about the recognition and cleavage sites for both restriction enzymes and DNA methyltransferases together with their commercial availability ...

A physical map of human Alu repeats cleavage by restriction endonucleases

open access: yesBMC Genomics, 2008
Background Alu repetitive elements are the abundant sequences in human genome. Diversity of DNA sequences of these elements makes difficult the construction of theoretical patterns of Alu repeats cleavage by restriction endonucleases.

Fused eco29kIR- and M genes coding for a fully functional hybrid polypeptide as a model of molecular evolution of restriction-modification systems

open access: yesBMC Evolutionary Biology, 2011
Background The discovery of restriction endonucleases and modification DNA methyltransferases, key instruments of genetic engineering, opened a new era of molecular biology through development of the recombinant DNA technology.

Universal Linker and Ligation Procedures for Construction of Genomic DNA Libraries Enriched for Microsatellites

open access: yesBioTechniques, 1999
Microsatellite loci are highly informative genetic markers useful for population genetic studies, linkage mapping and parentage determination. Methods to identify novel microsatellite loci commonly use subtractive hybridization to enrich smallinsert ...

Restriction Fragment Length Polymorphism Linkage Map for Arabidopsis thaliana [PDF]

open access: yes, 1988
We have constructed a restriction fragment length polymorphism linkage map for the nuclear genome of the flowering plant Arabidopsis thaliana. The map, containing 90 randomly distributed molecular markers, is physically very dense; >50% of the genome is ...

Mechanism of DNA Recognition by the Restriction Enzyme EcoRV

open access: yesJournal of Molecular Biology, 2010
EcoRV, a restriction enzyme in Escherichia coli, destroys invading foreign DNA by cleaving it at the center step of a GATATC sequence. In the EcoRV-cognate DNA crystallographic complex, a sharp kink of 50 degrees has been found at the center base-pair step (TA).

Biomolecular computers with multiple restriction enzymes

open access: yesGenetics and Molecular Biology, 2017
The development of conventional, silicon-based computers has several limitations, including some related to the Heisenberg uncertainty principle and the von Neumann “bottleneck”.

Pathological phenotypes and in vivo DNA cleavage by unrestrained activity of a phosphorothioate-based restriction system in Salmonella [PDF]

open access: yes, 2014
Prokaryotes protect their genomes from foreign DNA with a diversity of defence mechanisms, including a widespread restriction–modification (R–M) system involving phosphorothioate (PT) modification of the DNA backbone. Unlike classical R–M systems, highly
