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 ...

Using high-speed atomic force microscopy (HS-AFM), the Kanazawa University team led by Mikihiro Shibata filmed the dynamic movements of CaMKII at the single-molecule level. The images revealed that a ...

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).

Strings of sugars called polysaccharides are the most abundant biopolymers on Earth. Because of their versatile and environmentally friendly properties, these molecules could eventually replace some ...

Digestive enzymes are proteins in the body that help break food down. Some people with certain medical conditions might be unable to produce sufficient enzymes and require supplements. Digestive ...

A popular experiment that's recommended to demonstrate the functionality of enzymes is chewing a piece of bread for a moment, then paying attention to when it turns from a starchy flavor to begin ...
