Localization of L11 protein on the ribosome and elucidation of its involvement in EF-G-dependent translocation.
R.K.Agrawal, J.Linde, J.Sengupta, K.H.Nierhaus, J.Frank.
L11 protein is located at the base of the L7/L12 stalk of the 50 S subunit of the Escherichia coli ribosome. Because of the flexible nature of the region, recent X-ray crystallographic studies of the 50 S subunit failed to locate the N-terminal domain of the protein. We have determined the position of the complete L11 protein by comparing a three-dimensional cryo-EM reconstruction of the 70 S ribosome, isolated from a mutant lacking ribosomal protein L11, with the three-dimensional map of the wild-type ribosome. Fitting of the X-ray coordinates of L11-23 S RNA complex and EF-G into the cryo-EM maps combined with molecular modeling, reveals that, following EF-G-dependent GTP hydrolysis, domain V of EF-G intrudes into the cleft between the 23 S ribosomal RNA and the N-terminal domain of L11 (where the antibiotic thiostrepton binds), causing the N-terminal domain to move and thereby inducing the formation of the arc-like connection with the G' domain of EF-G. The results provide a new insight into the mechanism of EF-G-dependent translocation.

Figure 1.
Figure 1. Stereo-view comparison of the cryo-EM structures of L11-depleted 70 S ribosome and wild-type (control) ribosome. (a) L11-depleted ribosome and (b) control ribosome.[33] The ribosome maps are shown from the 30 S subunit side. Arrows in (a) point to the absence of density in the stalk-base (Sb) region, while in (b) they point to the additional density in the control. Landmarks of the 50 S subunit: L1, protein L1; St, stalk; Sb, stalk base. Landmarks of the 30 S subunit: h, head; b, body; and sp, spur.

Figure 2. Stereo-view representation of the fitting of the X-ray structure of L11 into the corresponding cryo-EM density. The stalk-base regions of cryo-EM densities of control (grey) and L11-depleted (blue) 70 S ribosomes are shown as wire-mesh structures. (a) Results of fitting the X-ray structure of the complete L11-58 nt RNA complex[22] as one rigid body (see Gabashvili et al.[28]). The RNA portion is not shown. (b) The optimum fit obtained for the NTD (N, yellow) by rotating it around a pivoting point between the two proline residues, 73 and 74, of the linker between the CTD (C, green) and NTD.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
