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

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 ...

A collaboration between Merck & Co and Codexis, Inc. has resulted in the development of a nine-enzyme, chain-reaction approach for making the HIV drug islatravir. In their paper published in the ...

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 ...

Enzymes often elicit envy from organic chemists. Highly evolved by nature, these biocatalysts can carry out reactions with a selectivity that surpasses most synthetic catalysts. Yet they act on such a ...

All organisms, including plants, have developed mechanisms of defence against pathogenic and other challenges, and thus solve a key biological problem: survival. A stunning example of this in humans ...

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 ...

Enzymes are proteins that catalyze biochemical reactions. In addition to performing biochemical reactions in living organisms, enzymes also function in vitro, which allows for the use of enzymes in ...

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 ...
