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).

Restriction Enzyme-Mediated DNA Family Shuffling
2014DNA shuffling is an established recombinatorial method that was originally developed to increase the speed of directed evolution experiments beyond what could be accomplished using error-prone PCR alone. To achieve this, mutated copies of a protein-coding sequence are fragmented with DNase I and the fragments are then reassembled in a PCR without ...

Programmable DNA-Guided Artificial Restriction Enzymes
ACS Synthetic Biology, 2017Restriction enzymes are essential tools for recombinant DNA technology that have revolutionized modern biological research. However, they have limited sequence specificity and availability. Here we report a Pyrococcus furiosus Argonaute (PfAgo) based platform for generating artificial restriction enzymes (AREs) capable of recognizing and cleaving DNA ...

Recognition of DNA by Type II Restriction Enzymes
1989Publisher Summary This chapter discusses the recognition of DNA by type II restriction enzymes. A restriction/modification (R/M) system must possess two enzyme activities, the restriction endonuclease and the modification methylase, both of which are dependent on the recognition of the same DNA sequence.

Restriction enzyme studies on human highly repeated DNAs
Experientia, 1982Various restriction enzymes digest human highly repeated homogeneous DNA to discrete fragments, some of which are present in the male and absent in the female. The male specific 2.4 kilobase HaeIII fragment corresponds to human male satellite DNA IV.

Restriction enzyme analysis of human leukemic mitochondrial DNA
Leukemia Research, 1980Abstract Mitochondrial DNA from both normal human tissue and leukemic human leukocytes (AML and CML) were analyzed by restriction-enzyme digestion, polyacrylamide gradient gel electrophoresis and ethidium bromide staining. Both normal and leukemic human mitochondrial DNA show molecular heterogeneity from individual to individual.

DNA fingerprinting of yeast strains by restriction enzyme analysis
Research in Microbiology, 1994Restriction endonuclease analysis was used as a new method to obtain genomic DNA fingerprints in yeast. Fifteen yeast strains belonging to the genera Saccharomyces and Zygosaccharomyces were examined. Restriction fragments obtained with ApaI or KspI endonucleases were separated by SDS-PAGE and silver-stained.

What is the function of DNA restriction enzymes?
Trends in Biochemical Sciences, 1977The message of these figures is that in terms purely of economic cost it would make sense to mount a global vaccina- tion program against smallpox, even if the disease could never be eliminated. The hope of eradicating smallpox altogether rests on the fact that there seems to be no animal reservoir from which the human population can be reinfected, nor

Structures and mechanisms of DNA restriction and modification enzymes
Quarterly Reviews of Biophysics, 1979DNA restriction and modification enzymes are responsible for the hostspecific barriers to interstrain and interspecies transfer of genetic information that have been observed in a variety of bacterial cell types. Although the phenomenon of host specificity was initially observed in the early 1950s (Luria & Human, 1952; Bertani & Weigle, 1953 ...

Resistance of Tumor-Derived DNA to Restriction Enzyme Digestion
Cancer Investigation, 1990The major finding of this work is that there are specific restriction enzyme inhibitors present in "purified" tumor DNA which cause partial digestion patterns when tumor DNA is digested by standard procedures with any of three commonly employed restriction enzymes (HindIII, KpnI, XbaI).
