Protein Synthesis and Site of Action of Antimicrobials that Inhibit Protein Synthesis

What steps in protein synthesis ..

Tetracycline Hydrochloride mode of action is as a protein synthesis inhibitor via an aminoacyl-tRNA binding mechanism to the 30S subunit. Mode of resistance is the loss of cell wall permeability.
Note, Tetracycline can lower red blood cell count and cause anemia, because of this I would not use with injured fish, as this is the last thing you want to do with a bleeding fish.

Antibiotics that act by inhibitingfolic acid biosynthesis include the sulfonamides and trimethoprim.

Antibiotics That Inhibit Protein Synthesis | SpringerLink

Bacitracin is a polypeptide antibiotic produced by Bacillus species. It prevents cell wall growth by inhibiting the release of the muropeptide subunits of peptidoglycan from the lipid carrier molecule that carries the subunit to the outside of the membrane Teichoic acid synthesis, which requires the same carrier, is also inhibited. Bacitracin has a high toxicity which precludes its systemic use. It is present in many topical antibiotic preparations, and since it is not absorbed by the gut, it is given to "sterilize" the bowel prior to surgery.

Indeed, this has been the case; the following antibioticshave been developed as inhibitors of cell wall synthesis:

Tetracycline Hydrochloride is a naturally occurring Tetracycline used in the treatment of bacterial infections that are generally gram-positive such as Streptococcus and SOME gram-negative infections in fish.
It interferes with the production of proteins that the bacteria need to multiply and divide (bacteriostatic). However many bacterial pathogens have developed resistance to Tetracycline Hydrochloride.

inhibits the protein synthesis of bacteria?

Kanamycin and tobramycin have been reported to bindto the ribosomal 30S subunit and to prevent it from joining to the 50Ssubunitduring protein synthesis. They may have a bactericidal effect becausethisleads to cytoplasmic accumulation of dissociated 30S subunits, which isapparently lethal to the cells.
