- Abstract:
-
There is an ongoing debate as to how urea denatures proteins in solution. Using a combination of neutron scattering and computer simulation of a model peptide, KGPGK, it was found that the ionic strength and pH have a significant impact on the urea-peptide interaction. From the work presented here, it appears that urea first and foremost decreases the charge-based interactions in solution, such as the TFA-TFA association, before interacting with the peptide backbone via hydrogen bonds. This g...
