Scientists studying a COVID-19 coronavirus enzyme at temperatures ranging from frosty to human-body warm discovered subtle structural shifts that offer clues about how the enzyme works. The findings ...
Researchers have uncovered the structure of an enzyme that is crucial for maintaining an adequate supply of deoxyribonucleotides in human cells. Their new structure also reveals the likely mechanism ...
HANOVER, NH – By revealing the architecture of an essential enzyme in a parasite, Dartmouth researchers are helping address a public health issue. Researchers in the laboratory of Amy Anderson, ...
Ten years ago, researchers obtained the first crystal structure of Dicer, a key enzyme in a biological process called RNA interference (RNAi). In RNAi, a process also known as gene silencing, a short ...

Although many organisms capture and respond to sunlight, enzymes - proteins that catalyze biochemical reactions - are rarely driven by light. A new study captures the full cycle of complex structural ...
UPTON, NY—Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first ...
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...
The latest short science news items from C&EN. The team proposes that SAM plays a dual role in the reaction. It donates a methyl group to the enzyme’s cobalamin cofactor and then serves as a base when ...
