Recognition of cognate transfer RNA by the 30S ribosomal subunit.

  ABSTRACT  
 
Crystal structures of the 30S ribosomal subunit in complex with messenger RNA and cognate transfer RNA in the A site, both in the presence and absence of the antibiotic paromomycin, have been solved at between 3.1 and 3.3 angstroms resolution. Cognate transfer RNA (tRNA) binding induces global domain movements of the 30S subunit and changes in the conformation of the universally conserved and essential bases A1492, A1493, and G530 of 16S RNA. These bases interact intimately with the minor groove of the first two base pairs between the codon and anticodon, thus sensing Watson-Crick base-pairing geometry and discriminating against near-cognate tRNA. The third, or "wobble," position of the codon is free to accommodate certain noncanonical base pairs. By partially inducing these structural changes, paromomycin facilitates binding of near-cognate tRNAs.

Fig. 2. Complex of the 30S subunit with mRNA from a U[6] hexanucleotide and a cognate tRNA-ASL. (A) Overview of the complex. The 50S interface side of the 30S subunit is facing the reader, and important elements have been given standard colors that are used throughout the figures, namely, ASL at the A site (gold), codon from the U[6] hexanucleotide at the A site (purple), 3' end of 16S RNA that mimics mRNA at the P site (green), P site tRNA mimic introduced by helix 6 from a neighboring molecule (dark blue), and protein S12 (tan). (B) Stereo view showing details of the A and P sites, colored as in (A), with, in addition, helix 44 (cyan, right), helix 34 (blue, left), 530 loop (green, left), and paromomycin (yellow sticks, within helix 44). The hydrogen bonds responsible for the codon-anticodon interaction at both the A and P sites are shown as red lines.
Figure 3.
Fig. 3. Stereo views showing interactions of the ribosome with the codon-anticodon base pairs. The tightness of the interactions is shown by the semitransparent van der Waals surface. (A) In the first position, A1493 binds in the minor groove of the A36-U1 base pair. (B) In the second position, G530 and A1492 (both brown) act in concert to monitor the A35-U2 base pair. (C) The third (wobble) position, showing the G34-U3 base pair. C1054 stacks against G36 of the ASL. U3 interacts with G530, and indirectly through a Mg2+ ion (magenta) with C518 and residue Pro48 (E. coli Pro44) from protein S12 (gray). The base pair seems closer to Watson-Crick geometry. (D) The third position in the presence of paromomycin, with the expected GU wobble pair. The interactions with the ribosome are similar to those in (C).
