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 ...

SANTA CRUZ, CA — 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 ...

The first structure of a lipin enzyme, which carries out an important step in the production of triglycerides, the main reservoir for long-term energy storage, will help scientists to better ...

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 ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

Scientific research requires patience. The rewards are not always immediate, and the technology needed does not always exist. Michael A. Trakselis, Ph.D., professor and director of graduate affairs ...

The structure of a key enzyme involved in protein production is revealed by cryo-electron microscopy (cryo-EM). Using cryo-EM, researchers at Goethe University (Frankfurt, Germany) shed light on ...

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 ...

For the first time, the structure of a DNA enzyme complex implicated in infertility and cancer has been obtained using cryo-electron microscopy (cryo-EM). A collaboration of researchers, led by ...
