Structure validation with map-likelihood phasing. The atomic model in PDB entry 2gn5
was used with amplitudes of structure factors from 20 to 2.6 Å. Structure-factor amplitudes were from selenomethionine-containing gene 5 protein at λ = 0.9794; they consisted of the FP values output by SOLVE (Terwilliger & Berendzen, 1999) when run on the gene 5 protein MAD data (Skinner et al., 1994). (a) and (b) are σA-weighted maps. (c) and (d) are from map-likelihood phasing as described in the text. The atomic coordinates of residues 60–70 of PDB entry 2gn5
are overlaid on the map in (a) and (c); those of the same residues from 1vqb
are overlaid in (b) and (d). The maps are all contoured at 1σ. |
