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 ...
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 ...
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 ...
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, ...
A structural model of the telomerase enzyme shows how the binding domain (purple) tethers one end of the RNA component of the enzyme. (Image credit: Jansson et al., ) Researchers at UC Santa Cruz have ...
While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...
