Figure 4.
Figure 4. RNA-binding regions of S7. (a) Electrostatic
surface potential of S7. The potential displayed represents a
range from -12 to +12 k[B]T, shown with red as negative and blue
as positive. The surface potential calculation and display was
done using the program GRASP [84]. (b) Ribbon diagram of a
similar view, showing residues that are likely to be involved in
RNA-binding. Basic residues are shown in blue and
solvent-exposed hydrophobic residues are shown in yellow. The
red residues R76 and A116 correspond to the sites of crosslinks
to 16S RNA. The figure was produced using the program MOLSCRIPT
[82].
