Electron-density map (blue, 2m|Fobs| − D|Fcalc|, 1.0σ; green, m|Fobs| − D|Fcalc|, 3.0σ; red, m|Fobs| − D|Fcalc|, −3.0σ) calculated from phases directly after the masked electron densities shown in Fig. 3(c) were used as a model for molecular replacement in the 3.0 Å resolution data set (Table 2). The WbdD model (yellow) and the SAM cofactor (white) are shown as sticks. |
