Fig. S5.
Positive and negative density for even and odd maps. Density surrounding positively charged amino acids is shown on top, with green representing strong positive density and red representing weak, negative density. Density surrounding negatively charged amino acids is shown in green and the negative density in red with the same threshold on the bottom. We further draw attention to the negative cloud-like density (Insets) that surrounds the negatively charged residues. Finally, it should be noted that the half maps, displayed here, are at the closest threshold to the combined maps displayed in other figures. Small density variations do exist when comparing half density maps and combined density maps.
