The Carbohydrate-Active enZYme (CAZymes) classification system is a database that contains the knowledge of enzymes that are involved in the formation and break down of complex carbohydrates and ...

Cell-free systems designed to perform complex chemical conversions of biomass to biofuels or commodity chemicals are emerging as promising alternatives to the metabolic engineering of living cells.

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 ...

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 ...

Enzymology is the study of enzymes and enzyme-catalyzed reactions. Enzymes are biological catalysts that accelerate the rate of biological reactions. They can also perform multiple reactions ...

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 ...

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 ...

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 ...
