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, ...

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 ...

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, ...

What are the underlying forces and mechanisms that enable enzymes to accelerate reactions? "Quite recently, we have found that there are enzymes that enhance reaction rates by factors as large as 10 ...

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 ...

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 ...

The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and ...

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 ...

Enzymes catalyze the critical chemical reactions that help build and power living organisms. But chemists studying the origin of life on Earth face a vexing question: How did these metabolic reactions ...
