WebThis step involves long centrifugation times to bring down 70S ribosomes as well as dissociated 30S and 50S ribosomal subunits. Minimal centrifugation conditions can be used to primarily pellet 70S rather than 50S or 30S subunits. ii. If necessary, repeat two or three times until a clean pellet is obtained. WebErythromycin, a macrolide, binds to the 23S rRNA component of the 50S ribosome and interferes with the assembly of 50S subunits. Erythromycin, roxithromycin, and clarithromycin all prevent elongation at the transpeptidation step of synthesis by blocking the 50S polypeptide export tunnel.
