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 ...

Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

Enzymes act as catalysts within the living cells and are made up of proteins. All chemical reactions occurring in a living organism are dependent on the catalytic actions of enzymes, and this is why ...

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 ...

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 ...
