Restriction enzyme fingerprinting was applied to 72 transferable trimethoprim resistance plasmids to examine aspects of their epidemiology and molecular relatedness. These plasmids had previously been ...

Restriction enzymes are essential tools for recombinant DNA technology that have revolutionized modern biological research; however, they have limited sequence specificity and availability. The ...

Research by Professor of Chemical and Biomolecular Engineering Huimin Zhao and graduate student Behnam Enghiad at the University of Illinois is pioneering a new method of genetic engineering for basic ...

The biological function of restriction enzymes is derived from the defense of foreign DNA from invading cells. The restriction-modification system of bacteria makes the DNA bases of bacteria to be ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

Mek & Tosj on Monday released a new version (2.0) of EnzymeX, a Mac OS X-only program designed to assist molecular biologists in their work with restriction enzymes. The new version touts over 50 new ...

Figure 1: Enzymatic ligation assisted by nuclease (ELAN) reaction scheme and results. Once DNA fragments with unique and compatible restriction sites have been found or made, DNA molecules can be ...

RNA interference technology provides a rapid means for assessing the effects of loss of function of any gene 1,2,3,4,5. RNA interference specifically reduces a single mRNA species by introducing its ...

Enzyme engineering is an enzyme technology. With the rapid development of enzymology research, especially the promotion of enzyme application, the basic principle of enzymology is combined with ...

"We are able to show that caloric restriction slows down aging by preventing an enzyme, peroxiredoxin, from being inactivated. This enzyme is also extremely important in counteracting damage to our ...
