Figure 5
Difference electron density (Fafter − Fbefore, αcalc) map superimposed onto a Cα trace of thaumatin showing all the sites that were affected as a result of the UV exposure. The map is contoured at +5.0σ (green) and −5.0σ (red). The positive peaks identify structural elements that appear after the damage, while the negative peaks identify sites that are destroyed by the damage. |
