Proteins are long molecules that must fold into complex three-dimensional structures to perform their cellular functions.

When a protein folds, its string of amino acids wiggles and jiggles through countless conformations before it forms a fully folded, functional protein. This rapid and complex process is hard to ...

What puts the electronic pep in peptides? A folded structure, according to a new study. Researchers combined single-molecule experiments, molecular dynamics simulations and quantum mechanics to ...

A new study has described a potential mechanism that could help explain why some proteins refold in a different pattern than expected. The research showed that a type of misfolding, called ...
