Buffering the entropic cost of hydrophobic collapse in protein chains.
Direct inspection of high-resolution protein structures reveals that backbone dehydration promotes extra conformational freedom in the peptide bond, especially when the residue is not involved in secondary structure. The results imply a buffering effect that lowers the entropic cost of hydrophobic collapse. (c) 2004 American Institute of Physics.
