Creating the local modified density function gx(Δx). (a) Density in the IF5A electron-density map is shown with contours at 1.5σ. The atomic model used to calculate the map is shown and the central point (`x') is marked with an asterisk. (b) Modified local density gx(Δx) calculated using (5) corresponding to the map in (a) is shown. All electron-density maps were created with MAPMAN (Kleywegt & Jones, 1996) and O version 8.0 (Jones et al., 1991). |
