Recognition Sequence of a Restriction Enzyme
Nature New Biology, 1973Restriction endonuclease EcoRII makes about twenty double-stranded breaks per molecule of λh80 DNA. The 5′-terminal sequences are pC-C-A-G-G and pC-C-T-G-G. These are complementary and rotationally symmetrical, showing how the enzyme may produce DNA fragments with short cohesive ends.

Endonucleases, such as the restriction enzyme EcoRV, cleave the DNA backbone at a specific recognition sequence. We have investigated the catalytic mechanism of backbone phosphodiester hydrolysis by the restriction enzyme EcoRV by means of hybrid quantum

Restriction enzymes in cells, not eppendorfs
Trends in Microbiology, 1994Restriction enzymes are essential reagents to molecular biologists, but their relevance to bacterial populations is less obvious. Most bacteria encode restriction and modification systems and these are commonly considered to be a barrier to phage infection. Current evidence also supports a more general role for them in genetic recombination.

Restriction Enzyme Computation [PDF]
, 2003 In this paper implementation of an inner hair cell model, including macromechanics and mechanical to neural transduction process is presented and discussed. The well-known Meddis model will be use as the reference system, and a high level synthesis will provide a parametrizable implementation and a reusability code, which allows future refinements on ...

Control of steric hindrance on restriction enzyme reactions with surface-bound DNA nanostructures.
Nano letters (Print), 2008To understand better enzyme/DNA interactions and to design innovative detectors based on DNA nanoarrays, we need to study the effect of nanometric confinement on the biochemical activity of the DNA molecules.

Engineered Calcium-Precipitable Restriction Enzyme [PDF]
ACS Synthetic Biology, 2014 We have developed a simple system for tagging and purifying proteins. Recent experiments have demonstrated that RTX (Repeat in Toxin) motifs from the adenylate cyclase toxin gene (CyaA) of B. pertussis undergo a conformational change upon binding calcium, resulting in precipitation of fused proteins and making this method a viable alternative for ...

Class-IIS restriction enzymes — a review
Gene, 1991Class-IIS restriction enzymes (ENases-IIS) interact with two discrete sites on double-stranded DNA: the recognition site, which is 4-7 bp long, and the cleavage site, usually 1-20 bp away from the recognition site. The recognition sequences of ENases-IIS are totally (or partially) asymmetric and all of the characterized ENases-IIS are monomeric.

ATP-dependent restriction enzymes
2000The phenomenon of restriction and modification (R-M) was first observed in the course of studies on bacteriophages in the early 1950s. It was only in the 1960s that work of Arber and colleagues provided a molecular explanation for the host specificity.

The discovery of restriction and modification enzymes, which proved to be a major turning point in the progress of molecular biology, was a consequence of a bacteriological observation in the early 1950s (Luria and Human, 1952; Bertani and Weigle, 1953).

Model for wandering restriction enzymes
Nature, 1974I WISH to propose a model for those DNA restriction enzymes which, although requiring specific recognition sites, make a limited number of cuts at apparently random sites, far from the recognition sites.
