The Michaelis-Menten equation is used to describe the dynamics of an enzymatic reaction, in which an enzyme interacts with a substrate to generate some product before the enzyme is released. Cells are ...

Enzymes are biomolecules that perform specialized functions, such as the assembly or degradation of small molecules. The small size of enzymes (tens of nanometres) previously limited their study to ...

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists have now derived universal rules to enable the de novo design of optimal enzymes. As an example, they ...

Scientists first observed the biological phenomenon of restriction and modification in the 1950s, but they did not identify and isolate restriction enzymes until the late 1960s. 3 In 1970, Hamilton ...

Researchers have made use of cryo-electron microscopy to show the exact process of enzyme activation. Pandinus imperator, the emperor scorpion, is not only popular as a pet, but is also of interest ...

We have solved the crystal structure of the Holliday junction resolving enzyme T7 endonuclease I at 2.1 Å resolution using the multiwavelength anomalous dispersion (MAD) technique. Endonuclease I ...

(Nanowerk News) By combining artificial intelligence with automated robotics and synthetic biology, researchers at the University of Illinois Urbana-Champaign have dramatically improved performance of ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American When I first began making bread, the science ...

Cell biologists have made a significant advance, uncovering the key role of an enzyme in determining the physical structure and behaviour of cancer cells, including how they spread. The enzyme, called ...

LA JOLLA, CA—October 29, 2014—Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial ...
