Webb50 S is the larger subunit of the 70S ribosome of prokaryotes, i.e. bacteria and archaea. It 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 . WebbThe ribosomal proteins provide the structural framework for the 23S (28S in eukaryotes) rRNA that actually carries out the peptidyltransferase reaction. Thus, the 23S rRNA is an enzyme, and the ribosome is a ribozyme.
