Structures of the ribosome bound to EF-Tu-isoleucine tRNA elucidate the mechanism of AUG avoidance.

The frequency of errors upon decoding of messenger RNA by the bacterial ribosome is low, with one misreading event per 1 × 104 codons. In the universal genetic code, the AUN codon box specifies two amino acids, isoleucine and methionine. In bacteria and archaea, decoding specificity of the AUA and AUG codons relies on the wobble avoidance strategy that requires modification of C34 in the anticodon loop of isoleucine transfer RNAIleCAU (tRNAIleCAU< ...[more]

Visualization of ribosome-recycling factor on the Escherichia coli 70S ribosome: functional implications.

Project description:After the termination step of protein synthesis, a deacylated tRNA and mRNA remain associated with the ribosome. The ribosome-recycling factor (RRF), together with elongation factor G (EF-G), disassembles this posttermination complex into mRNA, tRNA, and the ribosome. We have obtained a three-dimensional cryo-electron microscopic map of a complex of the Escherichia coli 70S ribosome and RRF. We find that RRF interacts mainly with the segments of the large ribosomal subunit's (50S) rRNA helices that are involved in the formation of two central intersubunit bridges, B2a and B3. The binding of RRF induces considerable conformational changes in some of the functional domains of the ribosome. As compared to its binding position derived previously by hydroxyl radical probing study, we find that RRF binds further inside the intersubunit space of the ribosome such that the tip of its domain I is shifted (by approximately 13 A) toward protein L5 within the central protuberance of the 50S subunit, and domain II is oriented more toward the small ribosomal subunit (30S). Overlapping binding sites of RRF, EF-G, and the P-site tRNA suggest that the binding of EF-G would trigger the removal of deacylated tRNA from the P site by moving RRF toward the ribosomal E site, and subsequent removal of mRNA may be induced by a shift in the position of 16S rRNA helix 44, which harbors part of the mRNA.

The 70S ribosome modulates the ATPase activity of Escherichia coli YchF.

Project description:YchF is one of two universally conserved GTPases with unknown cellular function. As a first step toward elucidating YchF's cellular role, we performed a detailed biochemical characterization of the protein from Escherichia coli. Our data from fluorescence titrations not only confirmed the surprising finding that YchFE.coli binds adenine nucleotides more efficiently than guanine nucleotides, but also provides the first evidence suggesting that YchF assumes two distinct conformational states (ATP- and ADP-bound) consistent with the functional cycle of a typical GTPase. Based on an in vivo pull-down experiment using a His-tagged variant of YchF from E. coli (YchFE.coli), we were able to isolate a megadalton complex containing the 70S ribosome. Based on this finding, we report the successful reconstitution of a YchF•70S complex in vitro, revealing an affinity (KD) of the YchFE.coli•ADPNP complex for 70S ribosomes of 3 ?M. The in vitro reconstitution data also suggests that the identity of the nucleotide-bound state of YchF (ADP or ATP) modulates its affinity for 70S ribosomes. A detailed Michaelis-Menten analysis of YchF's catalytic activity in the presence and the absence of the 70S ribosome and its subunits revealed for the first time that the 70S ribosome is able to stimulate YchF's ATPase activity (~10-fold), confirming the ribosome as part of the functional cycle of YchF. Our findings taken together with previously reported data for the human homolog of YchF (hOLA1) indicate a high level of evolutionary conservation in the enzymatic properties of YchF and suggest that the ribosome is the main functional partner of YchF not only in bacteria.
