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 ...

WEST LAFAYETTE, Ind. - Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses. The Paramecium bursaria chlorella virus ...

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 structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

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.

Macrolides are an important class of antibiotics that includes drugs such as azithromycin and erythromycin, which are widely ...

Enzymes with specific functions are becoming increasingly important in industry, medicine and environmental protection. For ...

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 ...

CHAPEL HILL -- A study led by scientists at the University of North Carolina at Chapel Hill offers the first molecular explanation of how the body metabolizes and detoxifies cocaine and heroin. "We ...
