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 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 ...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the current pandemic of COVID-19, is the focus of many investigators seeking to find an effective vaccine or therapeutic.

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.

A single type of chemical structure that shows up again and again in modern medicine is the amide bond that links a carbonyl group (C=O) to a nitrogen atom. They're so ubiquitous that 117 of the top ...

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 ...

A team of biochemists at the University of California, Santa Cruz, has developed a faster way to identify molecules in the ...
