Radiation damage to the FABP4 ligand in 7fxp at 1.05 Å resolution. The negative maxima in r.m.s.d. of the Fo − Fc map after refinement are shown as green meshes at the carboxylate and the halogen atoms in the ligand, together with the B values of the atoms affected and their binding partners. Despite the damage to the Br atom, this data set retained enough anomalous signal for SAD phasing (see the first panel in Fig. 4[link]). Refinement of the anomalous scattering factors did not change f′(Br) and only slightly changed f′′(Br) from 2.9 to 2.7 e−, with no effects on the Fo − Fc peak heights.
