UW-Madison engineers squeeze secrets from proteins

...team developed a method to precisely calculate the entropy and determine how much of a protein's stability change upon confinement to attribute to energy and how much to entropy. "This is the important part of the calculation," de Pablo adds. Protein stability is an incredibly important property in myriad a...
