Antibiotics that inhibit protein synthesis are discussed. Background biochemistry information on translation is provided. Antibiotics presented include puromycin, aminoglycosides, tetracyclines, chloramphenicol, macrolides, lincosamides, streptogramins oxazolidinones, mupirocins, and peptide deformylase inhibitors....
In this lesson we'll first review the basic steps of building new proteins through protein synthesis. Then we'll look at two main ways that...
Protein synthesis is a multistep process where DNA is first transcribed into a molecule of single-stranded messenger RNA (mRNA). Then, the ribosome translates it with the help of transfer RNA (tRNA) into long strings of amino acids, which become proteins. Protein synthesis inhibitors...
MANY compounds are specific inhibitors of protein synthesis and the mechanism of their action has been much investigated. Not all compounds which inhibit protein synthesis in micro-organisms do so in ribosomal systems of mammalian origin, for example, chloramphenicol 1–3 . In yeasts an interesting ...

Zithromax is not a penicillin it is a type of antibiotic called a macrolide. Macrolides kill bacteria by inhibiting protein synthesis and blocking the assembly of the 50S ribosomal subunit, which is a structure in a cell that helps coordinate protein synthesis. Macrolides are unrelated to penicillin...
3a). As streptomycin is known to act as a protein synthesis inhibitor by binding to the small 16 S rRNA of the 30 S subunit of the bacterial ribosome, this suggests that the known mechanism of action for streptomycin in bacterial cells may also affect mammalian cells6, 30. For the ...
