The responsible enzyme is typically encoded by the ermBgene, and the phenotype is often referred to as MLSB. An efflux pump, encoded by the transferrable mefAgene, is also known to pump macrolides out of the cell, but confers a lower level of resistance than ermB(Clancy, et al., 1996).
What is the role of antibiotics in the cell wall?
The antibiotics form complexes with the D-Ala-D-Ala peptide termini of peptidoglycan precursors on the outer surface of the cell, which prevents the cell wall biosynthetic enzymes (i.e., the PBPs) from using them as substrates for transglycosylation and transpeptidation and , hence, impairment of cell wall integrity.
