A physical map of human Alu repeats cleavage by restriction endonucleases [PDF]
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.

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

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

On the DNA cleavage mechanism of Type I restriction enzymes [PDF]
Although the DNA cleavage mechanism of Type I restriction–modification enzymes has been extensively studied, the mode of cleavage remains elusive. In this work, DNA ends produced by EcoKI, EcoAI and EcoR124I, members of the Type IA, IB and IC families ...

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

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