How does tetracycline prevent translation?
Thus, the consensus mechanism of tetracycline-mediated inhibition of bacterial translation indicates that the antibiotic prevents the binding of aminoacyl-tRNAs to the A site, inhibiting the elongation phase.
How do antibiotics prevent translation?
Antibiotics targeting translation interfere with either the assembly or the processing of the ribosome, or with the proper utilization of charged tRNAs and translation factors (Fig. 1a, b; Table 1)2. Still, the exact modes of action and physiological responses to many such translation inhibitors are unclear.
How do antibiotics block protein synthesis?
They inhibit protein synthesis by binding to the 30S subunit of the ribosome. Similar to the aminoglycosides, tetracyclines inhibit the binding of amino-acyl tRNA to the A site of the ribosome. The 7S ribosomal protein is part of the binding site.
What antibiotics affect translation?
Erythromycin, a macrolide, binds to the 23S rRNA component of the 50S ribosome and interferes with the assembly of 50S subunits. Erythromycin, roxithromycin, and clarithromycin all prevent elongation at the transpeptidation step of synthesis by blocking the 50S polypeptide export tunnel.
How does tetracycline prevent protein synthesis?
The tetracyclines, which were discovered in the 1940s, are a family of antibiotics that inhibit protein synthesis by preventing the attachment of aminoacyl-tRNA to the ribosomal acceptor (A) site.
How does tetracycline and erythromycin stop the translation process?
They inhibit the initiation of translation in variety of ways by binding to the 30S ribosomal subunit, which is made up of 16S rRNA and 21 proteins. They inhibit the binding of aminoacyl-tRNA to the mRNA translation complex.
Which of the following antibiotic inhibits protein synthesis of bacteria?
This drug acts to inhibit bacterial protein and DNA synthesis. Puromycin is an antibiotic that prevents bacterial protein translation….Protein Synthesis Inhibitors.
| Drug | Target | Type |
|---|---|---|
| Chloramphenicol | Chloramphenicol acetyltransferase | enzyme |
| Chloramphenicol | Chloramphenicol 3-O phosphotransferase | enzyme |
| Linezolid | 23S ribosomal RNA | target |
What class of antibiotics work by inhibiting protein synthesis?
A third group of substances inhibit growth and M protein synthesis at the same concentration. These substances probably inhibit growth because they inhibit general protein synthesis, and are therefore specific inhibitors of protein synthesis. In this class are chloramphenicol, erythromycin, and the tetracyclines.
Which antibiotics inhibit the protein synthesis in bacterial cell?
Why some antibiotics inhibit protein synthesis in prokaryotes but not in eukaryotes?
For example, streptomycin stops protein synthesis in prokaryotic cells by binding to their unusual ribosomes. Streptomycin does not stop protein synthesis in eukaryotic cells because it does not bind to eukaryotic ribosomes.
