The results were published in the journal Nature Catalysis. The team investigated a well-known enzyme that has been studied extensively and is a textbook example of enzyme catalysis. Without the ...

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

Introduction Have you ever wondered how all the food that you eat gets digested? It is not only the acid in your stomach that breaks down your food—many little molecules in your body, called enzymes, ...

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 ...

Enzymes, the micro machines in our cells, can evolve to perform new tasks when confronted with novel situations. But what if you want an enzyme to do an entirely different job -- one that it would ...

Today's nearly $70 billion U.S. biofuels economy is powered by two technology toolboxes. Biochemical technologies—used to produce around 17 billion gallons of ethanol annually—leverage microorganisms ...

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 ...

(Phys.org)—A team of researchers working at Princeton University has come up with a new way to modify proteins to catalyze reactions that are unknown in nature. In their paper published in the journal ...

It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes – the biological ...
