Enzymes are biological molecules that play a crucial role in various biochemical reactions within living organisms. They act as catalysts, which means they speed up the rate of chemical reactions ...

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 able ...

A team has used neutron crystallography to image all of the atoms in a radical intermediate of a copper amine oxidase enzyme. They disclosed previously unknown details, such as precise conformational ...

COX-1 and COX-2 enzymes may be blocked by pain medications such as Advil and Vioxx in a more complex manner than was previously understood, a Queen's University study has found. COX-1 and COX-2 ...

A new study, published by a team of UBC Okanagan chemistry researchers, is creating a major rethink of how enzymes work. And how a quantum phenomenon helps an important enzyme control essential yet ...

Small-scale interactions of substrates with an enzyme's active site — over distances smaller than the length of a chemical bond — can make big differences to the enzyme's catalytic efficiency. Any ...

Pericyclic reactions, which involve concerted electron movement and a cyclic transition state, have long been a part of the synthetic chemist’s tool box. But finding enzymes that catalyze such ...

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 ...

When your wounds heal and your liver detoxifies a poison such as histamine you ingested, you can thank the class of enzymes known as copper amine oxidases for their assistance. Identifying the exact ...
