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 ...

Chemical engineers have developed an online tool that can accurately assign genes and proteins to unknown 'orphan' reactions, which are a major headache for biotechnology, drug development, and even ...

Using a series of more than 1,000 X-ray snapshots of the shapeshifting of enzymes in action, researchers at Stanford University have illuminated one of the great mysteries of life – how enzymes are ...

A startup company called Zymosense is developing and marketing nanosensors invented in Nigel Reuel's Iowa State lab. The new tools will help industries track and improve the enzymes used in ...

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 ...

WASHINGTON — When bacteria lose genes needed to make enzymes for important chemical reactions, defeat isn’t inevitable. Sometimes other enzymes will take on new roles to patch together a work-around ...

Scientists at the University of Basel report the development of a precisely controllable system for mimicking biochemical reaction cascades in cells. Using microfluidic technology, the team produces ...

A new study on Alzheimer's disease has revealed a previously unknown biochemical cascade in the brain that leads to the destruction of synapses, the connections between nerve cells that are ...

Enzymes all have specific purposes and capabilities. Time to learn about them.

One of the annoying things that happens when you track developing science is that you keep seeing interesting results on a topic, but none of them quite reaches the significance to justify a news ...
