Design of buried charged networks in artificial proteins

Buried charged networks in proteins are often important for their biological functionality and are believed to destabilise the protein fold. Here, the authors combine computational design, MD simulations, biophysical experiments, NMR and X-ray crystallography to design and characterise artificial 4α...
