Proteins are both flexible polymers and sophisticated nanoscale machines capable of performing a vast display of biological functionalities. All such functions rely on a remarkable trait: the ability of proteins to exploit termal energy to self-assemble (fold) into 3D structures form the chemical blueprints encoded into their amino-acid sequence and change shape in response to stimuli. Deciphering the rules and mecanisms by which proteins fold would have a profound impact in both basic science and biotechnology as it would allow designing proteins with new functionalities a la carte. However, in spite of large scale efforts during the last four decades, we still don't understand how proteins fold nor we are able to design proteins from scratch.
