In living organisms, every protein—a type of biological polymer consisting of hundreds of amino acids—carries out specific functions, such as catalysis, molecule transport, or DNA repair. To perform ...

Scientists at UCL have discovered a novel role played by ribosomes during the folding of new proteins in cells, described in their paper in Nature. Ribosomes, the cell's dedicated molecular machines ...

Proteins are like tiny machines in our bodies, helping with almost everything we do, including breaking down food, carrying messages between cells, and building and repairing tissues, like muscles and ...

Origami masters turn simple sheets of paper into ornate sculptures. In the origami of life, our cells must fold proteins into specific three-dimensional shapes before they can carry out their ...

Researchers have used nuclear magnetic resonance to observe a previously unseen intermediate state in which the protein lingers for an unexpectedly long time. Figure 1: A protein in its unfolded state ...

Add Yahoo as a preferred source to see more of our stories on Google. Although the Nobel Prizes in physics and chemistry are awarded separately, there is a fascinating connection between the winning ...

Proteins attain their functional three-dimensional structures through a finely tuned process of folding, which in the cellular milieu is considerably more complex than in vitro refolding assays.

The latest short science news items from C&EN. Proteins are vital for life, involved in virtually every biochemical process that makes life possible. They comprise one or more amino acid chains ...

Proteins are long molecules that must fold into complex three-dimensional structures to perform their cellular functions. This folding process occasionally goes awry, resulting in misfolded proteins ...
