Protein synthesis occurs in all living cells. Why, then, are some antimicrobial drugs that target protein synthesis selectively toxic to bacteria?

Expert Solution

Protein synthesis that occurs in all living cells are mediated by 80S ribosome, but that of microbes is done by 70S ribosome. Which is generally a target for inhibiting protein synthesis. Hence it can't affect the 80S ribosomes, as it is 70S specific.

However ,there are organelles like Mitochondria and chloroplasts which have 70S ribosomes which are prone to inhibition. So the drugs are made in such a way that they can't travell into another double membrane bound structure and are generally active in cytoplasm or else are destroyed. However it has been observed that despite all majors, mitochondria and chloroplasts are affected to a lesser extent which is again healed.

Give a thumbs up if you like the answer. Thank you

Antimicrobial Drugs 1. Why do antibiotics that target bacterial protein synthesis usually have a broader spectrum of activity compared to antibiotics that target the peptidoglycan integrity? 2. If your only treatment option is a highly toxic antibiotic (such as chloramphenicol), how could you adjust the treatment protocol to lessen its negative effects? 3. Suppose that a patient that suffers from a Gram-positive bacterial infection develops an allergic reaction to amoxicillin. What alternative antimicrobial treatment from the same general group of...

Describe the modes of action of antimicrobial drugs (ie: cell membrane, cell wall, protein synthesis, etc). Please provide an example drug for each. Explain the differences between antibacterial, antifungal, and antiviral drugs. Why is it important to know the difference in the drug targets? Discuss antimicrobial resistance. Be sure to include the mechanisms used by organisms and the implication on treatment options.

Determine whether each of the events involved in protein synthesis occurs in initiation, elongation, or termination.

Determine whether each of the events involved in protein synthesis occurs in initiation, elongation, or termination. Initiation Elongation Termination Answer Bank The small and large ribosomal subunits combine to form an initiation complex. The tRNA, mRNA, and new protein are released. The small ribosomal subunit attaches to an mRNA molecule. The ribosome moves down the mRNA strand to the next codon. An initial tRNA molecule pairs with the AUG codon of the mRNA molecule. Amino acids are transferred from tRNA molecules to the growing peptide chain. The ribosome reaches...
