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 ...

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 ...

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 ...

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 ...

Researchers have captured real-time "molecular movies" showing how an enzyme changes shape during catalysis. The study was published in Nature Communications.

The ensemble-function approach provides a quantitative catalytic model for serine proteases and identifies repeatedly evolved catalytic strategies. Credit: Science (2025). DOI: 10.1126/science.ado5068 ...
