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 ...

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 ...

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 ...

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 ...

RIKEN researchers have discovered how an enzyme modifies gene expression by targeting certain stretches of messenger RNA ...

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.

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 ...

Scientists at the University of California, Riverside, say they have discovered the structure of a novel RNA-modifying enzyme, ZCCHC4, and identified the mechanism that controls how this enzyme ...

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 ...
