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 ...

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 ...

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 ...

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 ...

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 ...

Man prides himself upon his growing mastery over nature, but in the ultimate biochemical analysis nature remains the master of man. With their most sophisticated laboratory glassware and corrosive ...

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 ...

Figure 1: Characterization of the carbonic anhydrase CDCA1 from a marine diatom. Gene-expression analysis shows that there is an increase in the abundance of cdca1 transcripts within 1 hour of ...
