Proteins and peptides are the primary functional polymers of medical biochemistry, directing virtually all cellular processes through their structural diversity, catalytic activities and signalling ...

Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein ...

How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although all organisms—even single-celled ones—have complex protein structures now, ...

Researchers had not yet identified ways in which they might affect biochemistry far from their physical structures. Now, in a new study published September 10 in the journal Cell, researchers from ...

The genetic code has given rise to the enormous diversity of proteins we see in nature—and rearranging the order of codons that make up a protein’s sequence leads to an immense variety of structure ...

Each cell in your body relies on precise communication with other cells to function properly. At the center of this process are the molecular switches that turn communication signals in the body on ...

An artificial intelligence system can now determine not only how proteins fold but also how they interact with other proteins, drug molecules or DNA. Biochemists and pharmaceutical researchers say the ...

Sometimes, life can be a real drag—especially if you’re a protein weighed down by unwanted baggage. Researchers have unveiled evidence that these ponderous proteins could be involved in a range of ...

A new nanopore-based method uses AI to recognize proteins from their electrical signatures, enabling fast, single-molecule, ...

Jane Richardson never considered herself an artist. Then, in the late 1970s, the structural biologist found herself in need of some colored pencils, pastels and sketching paper. Richardson, a ...

Amyloids are perhaps best known as a key driver of Alzheimer’s disease. The amorphous proteins, found throughout the human body, stick to nerve cells like plaque, choking off their function and ...
