Electron transport, the energy-generating process inside living cells that enables photosynthesis and respiration, is enhanced in peptides with a collapsed, folded structure. Credit: Moeen Meigooni.

Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism. Proteins are molecular origami at its finest. Classically, a protein is imagined as a ...

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

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 ...
