Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...

Nature has evolved thousands of enzymes to facilitate the many chemical reactions that take place inside organisms to sustain life. Now, researchers have designed artificial enzymes that sit on the ...

For many years, the structure, stability, and catalytic properties of water-soluble enzymes have been studied by analysing their crystal structures and by investigating their catalytic properties when ...

For the first time, researchers have succeeded in predicting how to change the optimum temperature of an enzyme using large computer calculations. A cold-adapted enzyme from an Antarctic bacterium was ...

Pericyclic reactions, in which electrons move in concert to rearrange a molecule’s structure, are standard tools for synthetic chemists. But examples of such transformations in nature are fairly rare.

Enzyme kinetics involves the measurement of the rate at which chemical reactions that are catalyzed by enzymes occur. Knowledge about the kinetics of an enzyme can reveal useful information about its ...

For the first time, researchers have successfully used computational simulations to modify an enzyme’s structure to increase the optimum temperature of a reaction. Researchers at Uppsala University ...

It’s pretty easy to grow vast quantities of microbes. It’s a lot harder to convert those microbes into something useful. For example, we’ve engineered algae that, when starved for nitrogen, will put ...

High-resolution cryo-electron microscopy makes it possible to study complex enzymatic processes in detail. With this method, a research team of the University of Potsdam and Humboldt-Universität ...

"What we're defining here is what evolution had to overcome, that the enzyme is surmounting a tremendous obstacle, a reaction half-life of 2.3 billion years." Knowing how long reactions would take ...
