The importance of protein synthesis

Similar to TnaC described above, the peptide SecM exists solely to stallthe ribosome synthesizing it. But unlike TnaC, which also requires thepresence of high levels of trytophan, SecM has an intrinsic stallingcapability. Stalling of the ribosome synthesizing SecM provides time fora downstream RNA helix on the same mRNA strand to unwind. Unwinding ofthis helix then allows for a new ribosome to bind and synthesize anew protein, SecA, a bacterial ATP-driven translocase that aids the passage ofnascent proteins across membranes in conjunction with SecY (see also ). When sufficient levels of SecA have been reached,SecA interacts with the SecM-stalled ribosome to pull on SecM, freeingit and allowing translation to resume (illustrated schematically inFig. 13). SecM, which serves no otherpurpose than to stall the ribosome, is released into the cell anddegraded.

The structural basis for TnaC-mediated translational stalling wasaddressed by obtaining a 5.8-Å cryo-EM map of the ribosome stalled byTnaC and high concentrations of tryptophan (Fig. 8). The cryo-EM datashows that the nascent chain adopts a distinct conformation in the exittunnel. We applied MDFF to obtain an atomic model of the entire ribosomeand the stalling nascent chain (Fig. 8F). The model allowed us to mapthe contacts between TnaC and the exit tunnel, as well as proposepossible communication pathways that would lead to inactivation of thecatalytic center of the ribosome (the so-called peptidyltransferasecenter, or PTC). One of the main findings was that two criticalribosomal residues at the PTC adopt conformations that are incompatiblewith cohabitation by release factors, which catalyze termination ofprotein synthesis.

Why is protein synthesis important

Due to great advances in the structural resolution of the ribosome, animpressive feat given its large size, the system is considered one ofthe hottest focal areas in molecular cell biology today. During theprocess of translation, the ribosome undergoes several conformationalchanges and binds to different factors that catalyze specificreactions. As detailed below, techniques to determine structure of theribosome can only image snapshots of the ribosome, often at medium tolow resolution. Atomic details of the interactions between the factorsand the ribosome, along with a dynamic description of the conformationalchanges of the ribosome itself, are crucial to understanding itsfunction.

The structure and function of the ribosome are fascinatinglycomplex. Two-thirds of the ribosome consist of ribosomal RNA (rRNA),while over 50 ribosomal proteins make up the rest. The geneticinformation is delivered to the ribosome by a messenger RNA(mRNA). Transfer RNAs (tRNAs) are adapter molecules, each equipped withan anticodon to match the codons in the mRNA, and charged with an aminoacid that corresponds to the anticodon as dictated by the geneticcode. The ribosome contains three tRNA-binding sites: A, P, and E (seeelongation cycle box, or watch a ). In addition to mRNA and tRNAs, the ribosomeinteracts with protein factors such as the elongation factors Tu (EF-Tu)and G (EF-G), that are important players in the so-called elongationcycle. The elongation cycle results in the addition of an amino acid tothe nascent peptide chain, and consists of three main steps. In thedecoding step, a ternary complex comprised of an aminoacyl-tRNA(aa-tRNA), EF-Tu, and GTP binds to the ribosome,leading to the recognition of the codon by the anticodon. The followingstep is the peptidyl transfer. Here the peptide chain bound to theP-site tRNA is covalently linked to the amino acid bound to the A-sitetRNA. In the translocation step, the position of the mRNA/tRNA complexshifts by one codon, accompanied by a ratchet-like motion of theribosomal subunits.

Microbial protein synthesis in rumen and its importance …

The translation of genetic information into proteins is essential forlife. At the core of this process lies the ribosome, a quintessentiallarge (2.5-4.5 MDa) molecular machine responsible for translatinggenetic material into functional proteins. In a growing cell, ribosomescomprise up to half of the net dry weight. Because of its fundamental rolein the cell, 50% of all efforts to develop antibiotics target bacterialribosomes, taking advantage of the structural differences between bacterialand human ribosomes.
