Ribosomes and antibiotics
WebbOne of the main targets of antibiotics that inhibit protein synthesis is the ribosome, which is the macromolecular complex responsible for the synthesis of proteins. The ribosome is composed of two subunits, the small subunit (30S in prokaryotes and 40S in eukaryotes) and the large subunit (50S in prokaryotes and 60S in eukaryotes). WebbIt is the site of inhibition for antibiotics such as macrolides, chloramphenicol, clindamycin, and the pleuromutilins. It includes the 5S ribosomal RNA and 23S ribosomal RNA . Despite having the same sedimentation rate, bacterial and archaeal archaeal ribosomes can be quite different. Structure [ edit]
