Researchers have used cryo- electron microscopy to elucidate for the first time the structure and function of a very small enzyme embedded in cell membranes. This enzyme builds complex sugar trees ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...

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 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 ...

Researchers have determined the atom-by-atom structure of the fermentation enzyme phosphoketolase by cryogenic electron microscopy. They identified details that were mistakenly characterized by X-ray ...

"This structure answers a long-standing question for how two essential regions, N-lip and C-lip, which are located on opposite ends of this protein in humans, come together to form a function enzyme ...

A research team at Leibniz-HKI has described a new enzyme that renders the highly toxic molecule malleicyprol harmless. Malleicyprol is considered an important virulence factor of Burkholderia ...

David Cantu and Tin Nguyen have received a 3-year, $599,999 grant from the National Science Foundation’s Cyberinfrastructure for Sustained Scientific Innovation (CSSI) Program to support the creation ...

Deep in your muscles, an enzyme called AMPD1 helps turn chemical fuel into usable energy. When it does not work well, muscles tire faster.
