Figure 2
Placed fragments and resulting map or structure for the test cases. (a) The three three-fragment substructures leading to structure solution in the case of PRD2 when using model helices of 14 alanines. Whereas the helices depicted in red and orange are common to all three solutions, the blue one is slightly different for two of them and partially overlapped and out of density for the third. The resulting electron-density map after expansion of the best solution is shown in cyan contoured at 1σ and including data extrapolated to 1.7 Å. (b) Located anomalous substructure shown as green spheres derived from the S atoms of hellethionin D (NMR structure; PDB entry 1nbl; Milbradt et al., 2003  ), the resulting electron-density map after expansion, shown in blue contoured at 1σ and including data extrapolated to 1.0 Å, and the polyalanine trace of the solution obtained for viscotoxin A1 after the first fragment. |
