~~==Overview==~~

<!--

~~Structural data about~~ the ~~early step of protein denaturation were obtained from cross-linked crystals for two small proteins~~: ~~barnase and lysozyme~~. ~~Several denaturant agents like urea, bromoethanol or thiourea were used at increasing concentrations up to a limit leading to crystal disruption (>or=2 to 6 M~~)~~. Before the complete destruction of the crystal order started~~, ~~specific binding sites were observed at the protein surfaces, an indication that the preliminary step of denaturation~~ is the disproportion of intermolecular polar bonds to the benefit of the agent "parasiting" the surface. The analysis of the thermal factors first agree with a stabilization effect at low or moderate concentration of denaturants rapidly followed by a destabilization at specific weak points when the number ~~of sites increase (overflooding effect)~~.

-Structural data about the early step of protein denaturation were obtained from cross-linked crystals for two small proteins: barnase and lysozyme. Several denaturant agents like urea, bromoethanol or thiourea were used at increasing concentrations up to a limit leading to crystal disruption (&gt;or=2 to 6 M).
