Figure 2
Comparison of the (Fobs,2 − Fobs,1, αcalc,1) (blue) and (Fobs,3 − Fobs,1, αcalc,1) (red) maps between a crystal without uridine (left figures) and a crystal with 1 M of uridine (right figures) contoured at −4σ. (a) Cys30–Cys115. (b) Cys64–Cys80. (c) Cys76–Cys94. (d) Met105. Crystals used are 12 (no uridine) and 16 (1 M of uridine in solution). Data were collected at room temperature. See Table S2 for diffraction statistics. |
