Ribonucleotide reductases (RNRs) play a crucial role in cells as the only source of the building blocks needed for DNA replication and repair. They use radical-based chemistry to catalyze the ...

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 ...

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 ...

Stony Brook University researchers are now able to address many long-standing questions about the formation of triglyceride molecules since they were able to visualize the structure of the lipin ...

Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction required to make new ...

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 ...

Kanazawa University, have captured real-time images showing how a key brain enzyme organizes itself to help memory formation. Their study, published in Nature Communications, reveals that the enzyme ...
