No more guesswork in drug design—atomic-resolution method exposes what trial and error keep missing
Drug discovery still too often relies on expensive trial and error. Researchers from ICTER show there is another way—building ...
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 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 ...
The first full-length structures of the human angiotensin-converting enzyme (ACE) have been determined by researchers from the University of Cape Town (UCT) using cryo-electron microscopy (cryo-EM).
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 ...
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 ...
