Figure 6
Fourier difference maps showing decarboxylation of Asp52 in (a) `nat', (b) `asc' and (c) `nitrate II4' crystals as a function of increasing dose (I: d2 − d1; II: d3 − d1; III: d4 − d1; IV: d5 − d1). The Fourier difference maps (red) are contoured at −0.25 e− Å−2. Note that the absorbed doses for the respective panels in (a)–(c) are not equal. |
