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...
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. ...
The streptogramins and related antibiotics (the lincosamides and macrolides) (MLS) are important inhibitors of bacterial protein synthesis. The key reaction in this process is the formation of a peptide bond between the growing peptide chain (peptidyl-tRNA) linked to the P-site of the 50S rib...
