Figure 1. Representative Electron Density MapsStereo views of F[o] − F[c] simulated annealing omit maps, computed with phases calculated from models in which the atoms of interest were deleted from the model used in refinement.(A) the ATP binding site of HslU, contoured at 5σ. Protein is shown as a ribbon diagram; ATP from the final HslUV model (average B factor 29.3) is shown as a ball and stick representation.(B) Carboxy-terminal segment of HslU (average B factor 119.1), contoured at 3σ (magenta) and 6σ (cyan). Residues of HslU which were omitted are shown in green, oriented with the carboxy-terminal Leu-444 at the bottom of the figure; neighboring residues of HslV are shown in standard colors (oxygen, red; nitrogen, blue; carbon, gray). Figure was prepared with BOBSCRIPT ([7 and 8]). The rendering and stereo pair generation of all figures was done with RASTER3D ( [25]) and IMAGEMAGIK (http://www.wizards.dupont.com/cristy/ImageMagick.html).
