It inhibits bacterial protein synthesis by binding to bacterial 50S ribosomal subunits; binding inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.  Erythromycin may be bacteriostatic or bactericidal depending on the organism and drug concentration. "}]
