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 ...

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 ...

All living things depend on millions of chemical reactions that happen constantly. Chemical reactions that keep you alive happen fast! When you eat food, breathe, play, and grow, all of these are ...

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 ...

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 ...

"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 ...

Reactions that can combine more than two molecular pieces in one go are a powerful way to build complexity quickly and save on costly isolation and purification. But the choreography for such a ...
