  ABSTRACT  
 
Initiation of translation at the correct position on messenger RNA is essential for accurate protein synthesis. In prokaryotes, this process requires three initiation factors: IF1, IF2, and IF3. Here we report the crystal structure of a complex of IF1 and the 30S ribosomal subunit. Binding of IF1 occludes the ribosomal A site and flips out the functionally important bases A1492 and A1493 from helix 44 of 16S RNA, burying them in pockets in IF1. The binding of IF1 causes long-range changes in the conformation of H44 and leads to movement of the domains of 30S with respect to each other. The structure explains how localized changes at the ribosomal A site lead to global alterations in the conformation of the 30S subunit.

Fig. 2. Interaction of IF1 with the 30S subunit. (A) Close-up of the IF1 binding site, with IF1 in purple, helix 44 in cyan, the 530 loop in green, and protein S12 in orange. These colors are used throughout Figs. 2 and 3. (B) Overview showing the position of IF1 (purple) with respect to the 30S subunit (gray). H44, 530 loop, and S12 are colored as in (A). H, head; Bo, body; N, neck; Sh, shoulder; P, platform. (C) Overview of the 30S showing helix 44, S12, and the 530 loop as in (A), but with the A- P- and E-site tRNAs modeled as described in the text, in dark blue, orange, and yellow, respectively. Comparison with (B) shows that IF1 would block the binding of A-site tRNA. (D) Stereo pair showing A1492 and A1493 in H44 buried into protein pockets formed by IF1 and a combination of IF1 and S12.
