Fig. 5: Detailed view of the interactions between the C-terminal tail of SmpB and the H5 stem-loop of tmRNA.
From: Structures of tmRNA and SmpB as they transit through the ribosome
Left: position of the H5 stem-loop at the entrance of the mRNA channel. Right: focus on the residues involved in the interactions between SmpB and H5 during the a pre-accommodation and b accommodation states. SmpB is purple, tmRNA is red and the surface of the ribosomal small subunit is light grey. Residues and nucleotides within 4 Å of each other are indicated, and the cryo-electron density map of SmpB is displayed.
