Although the myriad proteins found in all life are largely built from a set of 20 amino acids, many other amino acids exist in nature, and it remains a curiosity as to why some were ultimately ...

Nearly seven years ago, MIT scientists mapped the molecular structure of proteins in spider silk threads onto musical theory to produce the "sound" of silk in hopes of establishing a radical new way ...

What does body building, anti-aging cream and Bleomycin (a cancer drug) have in common? Peptides of course! Peptides are large molecules that are vital to life. If you were to take a protein and break ...

While DNA sequencing is a useful tool for determining what's going on in a cell or a person's body, it only tells part of the story. Protein sequencing could soon give researchers a wider window into ...

New research from Kyushu University in Japan could one day help provide humans living away from Earth some of the nutrients they need to survive in space or even give clues to how life started.

Alongside the classical 20 protein amino acids, which are used to build proteins, there are more than 1000 non-protein amino acids in nature. Occasional mistakes can mean these non-protein amino acids ...
