Figure 2. Topology of the decoding site. (a) 30S subunit
portion isolated from the 70S -fMet-tRNA^fMet -Phe-tRNA^Phe
-EF-Tu -GDP -kir complex, seen from the intersubunit space. The
architecture of the decoding site (dc) shows a density in the
region of the A-site codon (labeled with an asterisk) and a
low-density region (indicated by an arrow) within SH44. (b)
Ribbons representation of the docked atomic coordinates for
SH44, ribosomal protein S12 (S12), SH18 and the A site codon
(cd) from Ogle and co-workers21 within the density region
extracted from a.
