Fig. 6. Molecular interactions in the intersubunit bridges. (A)
Contact between S13 and L5 in ribosome I. (B) Contact between
S13 and L5 in ribosome II. Only the C traces for the
proteins are shown, because protein side chains are not clear in
the electron density of either ribosome. Residues that become
inaccessible to solvent (44) are indicated in orange for L5 and
in yellow for S13 and S19. The direction of view is indicated in
the center. (C) Molecular interactions in bridge B3. (D)
Molecular interactions in bridge B7a. (E) Molecular interactions
in bridge B6. Waters modeled at the interface are shown as red
spheres inside the water-accessible volume, green mesh. (F)
Close approach of phosphates at the subunit interface near
bridge B2c. Distances (in angstroms) between phosphate oxygens
are marked.
