Taking inspiration from enzymes, chemists have developed a catalyst to simplify the synthesis of ethers, key functional components of many drugs, foods, personal care items and other consumer goods.

Enzymes that catalyze multiple reactions from a reactant to a product often have evolved a way to get intermediates from one active site to another. Researchers report that one bacterial enzyme uses a ...

Enzymes, the workhorses of chemical reactions in cells, lead short and brutal lives. They cleave and assemble proteins and metabolize compounds for a few hours, and then they are spent. This sad fact ...

A new study published in the journal Nature Catalysis on February 10, 2020, reports the creation of a new artificial enzyme from two components, both non-biological in origin. This event marks the ...

Chemical reaction cascades have been generated in a cell using an artificial enzyme as a catalyst. Let there be light: An artificial metalloenzyme (blue) penetrates a mammalian cell, where it ...

Many chemical reactions require the input of energy to activate the transformation. This can often be in the form of heat, or chemical energy. One of the most efficient ways of introducing energy into ...

Enzyme engineering is a significant tool for fine-tuning enzymes to alter their stability, activity, and specificity. Enzymes are highly versatile macromolecular biological catalysts that can ...

University of Groningen scientists observed the characteristics of a single enzyme inside a nanopore. This revealed that the enzyme can exist in four different folded states, or conformers, that play ...

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 ...

Proteins are chains of amino acids, and each link in the chain can hold any one of the 20 amino acids that life relies on. If you were to pick each link at random, the number of possible proteins ends ...
