In the avalanche of research being generated on the human microbiome, it’s important to take a step back and think about the many basic facts of the system that we don’t know anything about. One ...

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 ...

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 ...

By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of ...

Mimicking natural evolution in a test tube, scientists have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth. Mimicking natural evolution in a test ...

XNAs, synthetic genetic polymers with alternative backbone chemistries not found in nature, are capable of forming XNAzymes, forming an all-artificial parallel to the more familiar—but not necessarily ...

Researchers at Duke University Medical Center have provided the first direct evidence in mice for the role of an enzyme that specifically controls the production of serotonin in the brain. DURHAM, N.C ...

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 ...
