Glycans are important complex carbohydrates found on cell surfaces that serve crucial roles in cell-to-cell communication, ...

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 ...

The film "Enzymes: Nature's Magic" explores the fundamental role enzymes play in life. Enzymes, though microscopic, are essential for digestion, metabolism, and growth in all living organisms. They ...

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 ...

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 ...

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 ...

When it comes to name-calling, Trinity College Dublin is a world-beater. For the past 15 years it has been the world centre for the classification and naming of newly discovered enzymes. The World ...

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 ...

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 ...
